Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coating on the blank copper-clad boards. Company ProfileWe know almost all electronic engineers got a problem to found a right manufacturer to make  PCB prototypes & small batch order because big factories don't want to make small orders, they always gave high price and very long delivery time, they can't provide fast delivery service.
