As we can see that increasing number of PCB suppliers appear in our searching engine when we are looking for a suitable [PCB Prototype](PCB Prototype), it may be confusing us which one is the reliable one, here I would like to help with the how to choose the proper PCB prototype supplier;
Fist of all, before you take one long term cooperation PCB prototype company as your partner, you have to figure out what your priorities are, Cheap & Fast &high quality these are 3 most important features for choosing a proper PCB supplier, most people want to have all of them, but most of the time, if it can contain two features, it would be a good one.
I did some research and I would like to make some recommendations here for reference.
**[JLCPCB](JLCPCB): FR4 Board from 1-6 Layers**
Good Features: Online Instant Quote ;
Cheap & High-Quality &Fast (depend on the shipping method)
Disadvantages: Only FR4&Rigid board for 1-6 board provided
If your design is most for 1-6 layers boards, then congratulation, [JLCPCB](JLCPCB) will be your best choice for PCB prototype supplier; For just 2$ you can get a 2 layer board with dimensions less than 100x100 mm which is just unbelievable cheap. And 4 layer boards are also very cheap, only $5 with dimensions less than 100x100 mm. The manufacturing time for 1-2 layer board, only cost 24 hours;
And now they also provide stencil and SMT service with coupons, PCB +SMT start from $2, also with promotion code [“JLCATH”](“JLCATH”) can get extra $2
**Szgdpcb: PCB prototype from 6-30 Layers (FR4/Flexible board)**
Good features：High-quality & Cheap &Fast
Disadvantage: only has the Chinese Web
If you have the design for more than 6 layers and you know Chinese well or get in contact with their sales, SZGDPCB would be a good choice for your Multiple layer PCB prototype.
Since multiple layer boards usually with buried holes or impedance etc, hard to get a quote online directly, usually need to be quoted by customer service after review your file, so get instant quotes will be a problem.
These two PCB prototype companies are best for I know before if you have a better choice, please feel free to share it with us.
