Geekcreit® 40pcs FR-4 2.54mm Double Side Prototype PCB Printed Circuit Board
A part of the review has been auto-translated.
Considering the very interesting price, you might as well buy them in all sizes ... We will necessarily find happiness in the right size ... By the way always choose a little too big then give a little grinding if it is necessary to reduce it ... The reverse will make you make a gas factory circuit where it will be necessary to stack so that the assembly fits on the PCB which is too small! What is great about these PCBs is the possibility of making very compact assemblies if you master SMD components with conventional through-hole components. I use 26 to 30AWG wire wrapper by soldering the two ends of SMD components format 1206 or 0603 which remain perfectly weldable on the studs at a pitch of 2.54mm. Here are some examples with hyper frequency radar charts. Of course, this type of card can be used for single models or 2 or even 3 copies, but especially not for mass production. But the successful and functional model will make it possible to go through the plotting software for a professional finish in large numbers.
Arrivati rapidamente senza danni da trasporto. Imballati bene con protezione in plasica espansa. PCB a doppio strato, realizzati bene, fori metallizzati perfetti, saldabilita' ottima, puliti bene. Questo e' il terzo ordine che faccio e ogni volta il prodotto e' sempre molto buono. Consigliati.
