ShenZhen ZhongYiLong Electronic Technology Co.,Ltd is an expert at PCB and PCBA manufacture, based in Shenzhen City, Guangdong, China. We was honored as an excellent supplier annually by many well-known companies both at home and abroad, Simultaneously, our HDI, prototype, medium and batch quantity of PCB and SMT (PCBA) were highly appreciated by Shenzhen High Tech Item Program and we were approved to locate in We have got the ISO 9001:2015 & ISO13485:2016 & IATF16949:2016 certifications. Now our PCB daily capacity reaches 1200 square meters, and PCB assembly can reach 10,000,000 units per month.We have rich experience in manufacturing PCB. Our daily capacity of PCB is 1200 square meters and we can deliver SS and DS PCB sample within 24 hours, 4-8 layer PCB in 3-5 working days. For the batch quantity for double side PCB, the lead time is 3-5 working days and 4-8 layer PCB is 5-8 days. The quick and fast lead time stably ensures our customer of quick research speed to occupying the market.For the convenience of better cooperating with our customers, we purchased and reestablished a SMT factory in 2005. By readjusting, rectifying and introducing into advanced management system, adding advanced high speed SMT machine, multifunctional SMT machine, 12 wet HAL lead free hot air reflow machine and ICT testing machine facilities, we ensure our customers with high quality, speedy SMT sample, prototype and medium batch quantity services. And we set special service such as high difficulty, high density IC Rework and IC soldering (such as BGA chip rework and soldering and BGA reballing).We have imported the advanced machinery from the US, Japan, German and Israel to improve our production and technical ability. We have set a great example in the PCB field of flying probe testing. We have a highly developed R&D division which has helped our factory successfully produce mechanical microvia and high density impedance and HDI."Always to think a little bit more for our customers, to do a little bit more for our customers, to set the quality as the route and the service as the basis" is the principle of JB. We let our customer feel our real fast, high quality and considerate service by source readjusting and department combination.
