  • How to Make a Professional Printed Circuit Board: the Complete Guide

    Producing plated through-hole vias is hard to do. In PCB production, they start with drilling the board first, then a galvanic process is used to get copper into the holes. After that, ohtorestit ist applied and dried. Then you need a double-sided light-exposure box and 2 films thar are perfectly aligned.... Usually, if you want double-sided, try to get the vias into the pins of your parts (resistors work best), etch both sides, drill, and solder your parts top and bottom. Free vias have to be soldered on both sides (tip: after soldering one side, don't cut too much of the wire you use as a contact. When cut too short, you risk pulling out the wire when you solder the other side - and you don't see this at a glance!)Best way to get professional double-sided PCBs is to have them produced...

You get 5 or 10 pcs of 100x100mm double sided boards, best quality with solder mask and silk print for less than 10$. Only drawback, if you need larger boards, prices go up sharply.

    You get photosensitive foils, that get laminated to the board after etching and drilling. Solder mask is then produced in the same way as the traces, component markings can be done with white foil and, again, exposing and developing.
