quesion about a smart PCB fabrication procedure

[faustojc]

Hy I am working in the develpment of an electronic project but I am a little ignorant about the PCD fabrication process and I would higly appreciate if somebody answer me the next questions:

For a small business developing a prototype, what would be the best PCB development procedure: Do you suggest that I develop the PCB design in a software such as PADS, protel or similar and then give that drawing to some company that has a CNC so the PCB can be machined. Is that the most appropiate procedute?



Once I have the PCB machined with holes and everything, how can I get the circuit componends solded, what kind of device could I buy to sold the components. five years ago solding was not a big deal because the IC pins were big enough to use a normal and cheap solder but no they are very small, so, could somebody tell me which machine I have to use please.

any further information would be higly appreciated
Thanks
Fausto

Hi Fausto,

I'm a PCB design engineer and I also had an experience in PCB fabrication in my previous company. The best way would be, after completing your PCB lay-out, you send it to the board house to be fabricated as a raw PCB, most companies don't just do the CNC drilling. If it's a 2 sided board then you could probably just fabricate it in your garage or your lab but if it's a multilayer, then you're gonna need help from the board vendors.

About the assembly/soldering, it could be done by hand, even if its a 0.0197" pitch 100 pin QFP. You just need the right tools. There are some real nice websites about hand soldering these type of components including chip capacitors etc.

This is only good if you're looking at 1-5 boards, it will take a lot of time on hand soldering but for greater quantities your gonna need the assembly house.

I hope this helps.
