Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 storey density multilayer professional supplier, to provide customers with high-precision high quality Shenzhen circuit board, printed circuit board technology, quality assurance, reasonable prices. Workers to the position, is about four weeks and the PCB BGA pads around the screen line alignment. Here is having awakened: BGA and sewage lines in the alignment process, in a timely manner is not fully aligned, pcb circuit board technology, even if the solder ball and pad shift of about 30%, still can be welded. Because the solder balls melting process, because of the tension between it and the pad and the pad is automatically aligned. After completion of the alignment operation, the PCB BGA rework on the workstation bracket, which is fixed to and BGA rework station level. Select the appropriate hot air nozzle (nozzle size that is slightly larger than the size BGA), then select the corresponding temperature curve, start welding, when the temperature curve is completed, cooling, will complete the BGA soldering. Branch Snyder Department of International Ltd. Shenzhen-Electronic Technology Co., Ltd. - The Department of Electronic Technology Company is a professional custom single-sided, double-sided, 2-40 storey density multilayer professional supplier of mobile phone circuit board technology, to provide customers with high-precision, high-quality circuit board in Shenzhen, quality assurance, reasonable prices. In the development process of the program, to be reasonable, must be accurate, understandable and feasible; in the first procedure, the Guangdong circuit board technology, should indicate the positive and negative film, the welding surface and the component side, and numbered or sign; the drilling process the aperture should indicate the type, pore size, pore size amount; when making holes, but it must specify the technical requirements for heavy copper layer and the backlight detection or determination; When the hole after plating, to indicate the size of the initial current and back A process normal current size of the original Guangdong circuit board technology, Newell record, pcb circuit board technology by the Department of Shenzhen-Electronic Technology Limited. Guangdong circuit board technology, Newell record, pcb circuit board technology is the Year of the Shenzhen-Electronic Technology Co., Ltd.
