Circuit board manufacturer will encounter the same a problem, a lot of customers provide only a plan in FPD format, or GPJ format images, just ask price. Of course we all know the simple single sided board also can quote the price, for more than four layers of plate, there is no way to offer. But production must offer PCB format drawings can. These are the first to buy PCB board members or first contact with the circuit board. After the request for quotation and production needs what information, see I described below, you know.

First of all, we must design the circuit diagram. The drawing must be used PCB software design, such as: CAM350 software. Protel 99 SE software . Powerpcb software. The simple single can use AutoCAD software produced is also possible. File must be in the format ( PCB, DDB, gerber.DWG, pcddoc etc.) as long as it is PCB format can. In addition to is abroad used some PCB software design drawings in the general domestic production can not, mainly domestic did not use this software, can be converted into PCB production data, PCB production. So it is also important to note that the.

Secondly, to determine the circuit board production technology. Such as: the plate thickness. Copper thickness. The ink color. The character color. Pad technology ( include: gold-plated. Immersion gold. A pewter. Without Tin Lead. Rosin. Nickel . OSP) and quantity. Production process to identify good together with PCB drawings to the manufacturer can begin to offer production.

In addition, if there is no drawings, can also provide PCB model. According to PCB model, copy board after the production can be
