BatchPCB - 303-284-0979

BatchPCB is an off-shoot of Spark Fun Electronics. Prices start at $10 for shipping (which includes the setup fee rolled in), and $2.50 per square inch. Boards are 2 layers, 0.062" thickness, 8 mil traces, 8 mil spacing, 20 mil minimum drill, 500 mil maximum drill, routed edges, soldermask and silk screen both sides, 1 ounce copper, no via or pad count limit, step and repeat OK, up to 10" x 15" boards. It seems they're cheaper up to 13 about square inches, when Advance Circuits becomes a better deal, unless you need more than 85 square inches. I have not used this vendor.
PCB Fab Express - 408-857-0039

These people have really aggressive pricing, starting at $13 (minimum quantity 5) for 2 layer, with mask and legend, up to 20 square inches. They also have 4 layer @ $33, 6 layer @ $48, and 8 layers @ $73, all with 5 day turn. Again, these are for 20 square inch boards. The prices increase for 40, 60, 80 and 100 square inches, but are still reasonable. Note that for 80 square inches, the prices are straight on par with $33/each deal from Advanced Circuits. There is also the odd requirement of all holes having to be plated through, and if you do have unplated holes (surcharge applies), only up to a 0.190 diameter. I've used these several times now, and been very happy with the results.
Advanced Circuits - 800-979-4722

These people are great. Boards up to 85 square inches (9.2" x 9.2"), 2 layer FR-4, 0.062, 1 ounce copper, plated through, solder mask both sides, silkscreen one side, square route (not sheared!), on a 5 day turn for $33 each, minimum 3. So for $99, you can get 3 of your boards from 1" by 1" on up to 85 square inches. That's a heck of a deal. I've used them for my last several boards, and the quality is awesome. Drills are on center, the silkscreen is sharp, dimensioning is dead on. And if you have an obvious CAD error (like inverted text), they'll call you about it. Highly recommended.
e-TekNet - 480-633-1809

I haven't personally used these folks yet, but I've seen at least 4 boards produced by them that are commercial products. The quality is very good. Looking at prices for 100 square inch boards 2 layer boards, they're cheaper by half than PCB Fab Express, and don't have the 60 square inch limit that Advanced Circuits has. I haven't compared prices for smaller sized boards, comparable to what I've produced at either of the other two companies mentioned.
Olimex - +359-32-626259

Olimex is based in Bulgaria. They have excellent rates, and offer solder mask and silk screening. They offer two basic sizes of boards, and will panelize your design (for free) to maximize the board usage. Using the lowest cost shipping option makes this an excellent value, but does result in longer turn around times. So far, my only real complaint was the drilling accuracy is not as tight as I would like. They seem to have 2-3mils of drill slop. I have turned 1 board with them as of 2000/12/03, and been very happy. The drill slop was annoying, but did not cause any problems. Tsvetan Usunov, the person who helped me get everything in order for submission, is very helpful, and responds quickly to e-mail.
Speedy PCB Prototype - 613-216-1913

"High quality PCB prototypes and PCB fabrication at very low prices. All boards are manufactured under ISO and UL." Added by request. I have not produced any boards with them. Based in Ottawa, Canada.
AP Circuits - 403-250-3406

Based in Canada, APC has reasonable rates and quick turns. My biggest complaint with them is that the board shearing is somewhat sloppy, and requires filing afterwards to clean it up. They do not offer solder mask and silk screening for the quick turn packages. I have turned 3 boards with them as of 2000/12/03, and been happy with the results, other than the shearing issue.
Bare Bones PCB - 800-979-4722

$0.50 per square inch + $25 per lot for 2-layer, FR-4, 0.062" thick, all plated holes, tin finish over 1-oz copper, cut to rectangle shape only, max size 12" X 16". No silk screen, no soldermask (bleh!). This is really just an alternative deal run by Advanced Circuits. I've never used this configuration, but it sounds like it's designed to compete with <A AP Circuits, mentioned above.
PCBPro - 503-829-9108

"Provides pcb design software, Circuit Boards, PCB prototype, PCB Schematic, pcb layout software, circuit board manufacturers, Printed Circuit Board Manufacturers and PCBs." Added by request. I have not produced any boards with them.
Express PCB - (no phone)

Express PCB is unique in that they provide free software for doing the board layout, which couples tightly with their production facilities. They offer four manufacturing options. "Standard" is 2 layer, plated through, no solder mask or silk screen, small orders ship next day, UPS. "Miniboard" is a 3.8" x 2.5" inch board, same as "Standard", but shipped via US Priority Mail. "10-day production" 2 layer plated through, includes solder mask and silk screen, routed to board perimeter, shipped UPS. "4-day production" is the same as "10-day", but higher cost. No phone number listed, try e-mail. I have not produced any boards with them.
PCB Express - 503-829-9108

PCB Express does 1, 2, 4 and 6 layer boards. Their basic pricing is available in the back of most electronics magazines. They seem to be more oriented towards business level prototype runs, as opposed to basement projects, like AP Circuits and Olimex. Their pricing is fairly high compared to these other two. I have not produced any boards with them.
Sierra Proto Express - 408-735-7137

Sierra Proto Express offers may different options. Their prices seem really good for multi-layer boards (4+), but don't really compete with Olimex for basic 1 or 2 layer boards. I have not produced any boards with them.
SMTH Circuits - 604-858-3970

SMTH Circuits offers 2 panels of 5" x 8" 2 layer boards with plated through holes and solder mask for $99. I have not produced any boards with them.
Pulsar, Inc - 847-233-0012

Pulsars ad say they offer 1 and 2 layer boards, SMOBC, LPI mask, through hole or SMT, nickle and gold plating, routing or scoring, and electrical testing. 3 day turn on 10 pieces of 1 or 2 layers is $249 (up to 30 square inches each), and includes tooling, artwork, LPI mask and legend. I have not produced any boards with them. Business & Industrial (12)

PCI Express? is positioned as the industry's third-generation I/O technology. First generation was ISA, second generation being PCI, and the third generation, PCI Express. The PCI Express technology has been ratified by the PCI Special interest Group (PCI SIG).

This third-generation I/O technology is needed today since PCI-based shared, parallel-bus-signaling technology is approaching its practical performance limits; it is increasingly difficult to scale-up bandwidth just by increasing the number of signal lines. More signal lines mean difficult clock-to-data skew management, creating complex PCB layout rules that make cost-effective implementations in the FR4 (current copper PCB) technology difficult. In addition, increasing the number of signal lines also increases the power dissipation. PCI Express allows for very high available bandwidth per pin with the ability to cost-effectively scale towards the 12 GHz limits of copper signaling technology.

PCI Express is designed to be a general-purpose serial I/O interconnect that can be used in multiple market segments, including desktop, mobile, server, storage and embedded communications. PCI Express can be used as a peripheral device interconnect, a chip-to-chip interconnect, and a bridge to other interconnects like 1394b, USB2.0, InifiniBand? and Ethernet. It can also be used in graphics chipsets for increased graphics bandwidth.

Key Features of PCI Express

Compatible with the current PCI software model: There are no changes required to the current Operating Systems while maintaining platform configuration and device driver interfaces. Enables smooth integration within future system allowing for broad industry adoption.
Serial architecture; Low-pin-count point-to-point connection (link): Does away with some of the limitations of parallel bus architectures by using embedded clock timing and differential signaling. The embedded clock lowers pin count (no separate control and clock pins are required) and makes data synchronization easier than in a parallel-based technology. Data can traverse a connector and cable scheme allowing flexible system partitioning. Serial technology enables unique and small form factors, reduces cost, simplifies board design and routing and reduces signal integrity issues. Point-to-point interconnect means no multiple hosts on same bus creating a bottleneck.
Bandwidth scalability and frequency and/or interconnect width: Each link can be scalable up in bandwidth by creating wider lanes to match applications use, such as a wider graphics port in Desktop or multiple bus bridges (PCI Express-to-PCI-X, -Gigabit Ethernet or - InfiniBand) in server platforms. The spec defines interface widths of x1, x2, x4, x8, x12, x16 or x32 lanes.
Embedded clock or CDR (Clock Data Recovery): Lowers pin counts, enables superior frequency scalability versus source synchronous clocking, and makes data synchronization easier.
Layered architecture: The architecture consisting of the Software layer, Transaction Layer, Data Link Layer and Physical Layer. Layering enables scalability, modularity and design reuse.
Packetized protocol: Time multiplexing versus circuit switching. This allows more than two-way communication at one time unlike circuit switching where only a two-way communications can occur. With packet based protocol there is no wasted bandwidth.
Advanced features: Aggressive power management, QoS, isochrony, hot attach/detach and RAS.PCB & ASIC DESIGN SERVICES

Rogers 4050, 4003 already introduced the 6600GT previously, so for now, we?ll skip the introduction and get straight to the actual product. Although it?s a minor thing in the grand scheme of features, the black PCB color and orange copper actually make this card attractive than standard versions we see from manufacturers these days. The heatsink and fan combination are a needed accessory to dissipate heat off of the modern GPUs. Not too impressively, the combo isn?t the quietest in the market. Even though we have seen slightly better cards noise wise, the difference between the loudest fans and the quietest ones isn?t all that much unless you are comparing a passively cooled heatsink to a bold design such as the ones from HIS. With that said, AOpen does offer something special that other companies tend to ignore on midrange adapters: RAMsinks. Throughout our testing, we?ve found the RAMsinks to be of little help in the overclocking department, but if the company can implement them without adding onto the cost, there?s nothing to complain about. The RAMsinks as well as the heatsink and fan combo performed rather well, as you?ll later find out in the evaluation.

The board layout of the card is fairly clean with everything lined up nicely. Unlike other heatsink and fan combinations, this particular design only requires a connection through the front side in order to stay intact. Similar to other 6600GT adapters, the AOpen edition offers eight pixel pipelines, 128MB of onboard memory and 128-bit memory interface with GDDR3 as the memory standard. The version we are looking at today is PCIe x16 with a single D-Sub, DVI and TV-Out ports.


As part of the package, the driver CD, manual, quick guide and the rest of the necessities are packed as well. However, what had us exciting were the actual games: Prince of Persia and Demo CD. Unfortunately, the demos are very outdated, but Prince of Persia is still a pretty solid title, though not recent in any regard. It has come to the point where we must commend AOpen for including something that other manufactures usually skip over. Manufacturer of Printed Circuit Boards (PCB)

What is the thickness and conctruction for multi-layer boards?

4-6 Layers: Limited to 14" in X or Y
Our standard construction builds .062 +/- .007.
We begin with a .028 mil core (.028 mils of laminate with 1 oz of copper laminated to each side. This will be layers 2 and 3 (the middle two). We print the design for the inner layers on each side then etch. We then laminate .012 mils of fiberglass (also known as "glass", "prepreg" or "dielectric") to each side and a sheet of half ounce copper foil on each side.

Our standard multi-layer construction looks like this:

4-Layer Construction:
Layer Stack-up:
1 copper foil, .0007 (1/2 ounce)*
.010 - .014 glass
2 copper clad, .0014 (1 ounce)
.026 - .028 glass
3 copper clad, .0014 (1 ounce)
.010 - 014 glass
4 copper foil, .0007 (1/2 ounce)*

6-Layer Construction:
Layer Stack-up:
1 copper foil, .0007 (1/2 ounce)*
.004 - .008 glass
2 copper clad, .0014 (1 ounce)
.012 - .014 glass
3 copper clad, .0014 (1 ounce)
.005 - .010 glass
4 copper clad, .0014 (1 ounce)
.012 - .014 glass
5 copper clad, .0014 (1 ounce)
.004 -.008 glass
6 copper foil, .0007 (1/2 ounce)*

*After plating; the surface copper thickness will be a minimum .0014 thickness on the outer layers.

Answers to common 2-6 Layer Inquiries:

Material Specs:
We use a variety of laminate material suppliers including Nanya and Isola.

- We are unable to test for controlled impedance. (Our Full Service and PCBpro Design check can build to set specifications but we have no way of determining what they should be or are).

- Currently we do not use teflon, high frequency, or flexible materials. We may offer other material types in the future.

- On our PCBexpress work we do not deviate in construction. If you have a special construction need you can use our PCBpro service found at www.China-PCB.org......PCBpro.com We would be able to do that construction with that service.

What is my board size limit?
Your design is setup on a panel with other customer orders to run in the process batch. The smallest board size is 0.35" (X or Y) for these services.

The largest board size allowed is 12 x 14 inches for all 2-6 layer services.

If your board requires larger panelization beyond these limits please try our PCBpro site: www.China-PCB.org......PCBpro.com

Can I order more than the service allows?
You may quote higher quantity or other lead time pricing: www.China-PCB.org......PCBpro.com

What about v-scores or tab routing?
PCBexpress does not offer v-score or tab routing.
Please use our quote form on www.China-PCB.org......PCBpro.com

Do you accept Auto-Cad (DXF) files?
We cannot accept Auto-Cad (DXF) files. We do not have a software to convert the format. Once your files have been converted to gerber and Excellon formats, we would be happy to accept them for processing.
