PCBA process outlined from Shenzhen Kingsheng PCBA Tech Co.,LTD (H.K. C-Alley Co.,LTD) . SMT and DIP are an integrated part of the way the PCB, the main difference is that the PCB SMT do not need to drill in the DIP PIN needs to be inserted into the parts of the foot wells have been drilled. SMT (Surface Mount Technology) from Shenzhen Kingsheng PCBA Tech Co.,LTD Surface mount technology, the main advantage placers are some of the micro and small parts mounted to the PCB, its production process is:PCB board positioning, printing paste, placement machines, reflow oven and had made test. With the development of technology, SMT can also mount some large size parts, such as body parts can mount some of the larger size of the motherboard. When SMT integrated part of positioning and size is very sensitive, in addition to quality and printing quality paste also played a key role. Now, Shenzhen Kingsheng PCBA Tech Co.,LTD has 8 Automatic SMT equipment lines with brand of Hitachi screen printer , FUJI NXT-ii&FUJI XPF-L Modules SMT machines, X-Ray and repair machine for BGA , Omron AOI machines.DIP (dual in-line package technology) from Shenzhen Kingsheng PCBA Tech Co.,LTD. If you still have any problems for PCBA making , please kindly send email to H.K. C-Alley Co.,LTD Sales department via sales2@c-alley.com. We will reply you questions within 1 day.

DIP or "plugins" that is inserted into the parts on the PCB version, use a larger size but because of the part is not available for placement or manufacturer SMT production process can not be used when in the form of plugin technology integration parts. Plugins and artificial robot industry is currently implemented in two ways, its main production process: adhesive stickers (tin-plated to prevent undue places), plug-in, testing, wave soldering, brush version (removed the furnace the process of leaving stains) and made test.

PCBA could lead to being rejected Blowholes / pinholes, paste back ?? complete wetting of solder onto the disc does not require welding or terminals, solder coverage does not meet the requirements, do not satisfy the anti-wetting phenomena lead surface mount soldering or through hole of solder filling requirements, tin ball violate minimum electrical clearance across the conductor should not be connected to the solder connections, solder connected across the adjacent nonconnected conductor or original solder disturbed, violent, according to the specified selection of the correct element, the element is not installed in the correct hole and so on. Situation pcbaproducts .Because PCBA production in the second half of electronic equipment manufacturers, downstream industries are therefore becoming the electronics industry. Almost all electronic devices need to support the printed circuit board,so the printed circuit board is a global electronic components market share in most products. Currently, Japan, China, Taiwan, Western Europe and the United States as the main printed circuit board manufacturing base.

After above standard process of PCBA , in order to get 100% quality of PCBA, we must 100% yeild by function testing. You only need to provide testing instructions and testing software to Shenzhen Kingsheng PCBA Tech Co.,LTD, then the engineer depatment from Shenzhen Kingsheng PCBA Tech Co.,LTD will make testing jig according to customers testing instructioons. Please note, there must have testing point from your PCB, which will be better for testing and for the quality control. So, before your design, you have to ask your R&D department to make sure there have testing point in the PCB. If you need quotation for PCB or PCBA from Shenzhen Kingsheng PCBA Tech Co.,LTD (H.K. C-Alley Co.,LTD) , please send email to sales2@c-alley.com, and including Gerber files and Bom list, Shenzhen Kingsheng PCBA Tech Co.,LTD can release quotation sheet for PCBA projects within 3 days.
