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 board, 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, six 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, Guangdong circuit board technology, which is fixed to and BGA rework station level. Select the appropriate hot-air nozzle (i.e., nozzle size slightly larger than the size BGA), Bluetooth circuit board technology, and then select the corresponding temperature profile, the welding start until the temperature profile is completed, cooling, will complete the BGA welding.

When pattern transfer, after the film with the film to indicate the surface and the photoresist film proper contact and exposure conditions of the test conditions to determine, then the exposure; semi-finished products after the exposure time to go to a certain place and developed; pattern plating When thickened, to be strict on the surface of the exposed copper parts cleaning and inspection; copper thickness and other process parameters such as current density, bath temperature; metal plating resist - when tin-lead alloy, to indicate the coating thickness Guangdong circuit board technology, Newell create Bluetooth circuit board technology by the Department of Shenzhen-Electronic Technology Limited. Guangdong circuit board technology, Newell create Bluetooth circuit board technology is the Year of the Shenzhen-Electronic Technology Co., Ltd.
