quality assurance
iPCB has passed ISO9001:2008, ISO14001, UL, CQC and other quality management system certifications, and produces standardized and qualified PCB products. We master complex process skills and use professional equipment such as AOI and Flying Probe to control production, X-ray inspection machines, etc. . Finally, we will use double FQC inspection of appearance to ensure shipment under IPC II standard or IPC III standard.
There are many equipment used in PCBA processing, mainly divided into two categories, one is patch, mainly machines, and patch machines.

The printer is located at the front end of the PCBA processing line, and its main purpose is to print solder paste or patch glue on PCB circuit boards. The working process is that after the mesh of the stencil of the printing machine is aligned with the PCB pad, the solder paste or patch glue placed on the stencil is printed on the PCB pad or the corresponding position through the movement of the squeegee for PCBA processing Prepare for component placement in the subsequent process. The main purpose of the dispenser is to apply solder paste or patch glue. The working process is to apply a prescribed amount of glue or solder paste on the required position of the PCBA device through the pressure of the vacuum pump. The advantage of the dispenser is that during the production process, there is no need to replace the production jig, which greatly shortens the production cycle and is suitable for small batch and multi-product production.

The placement machine is the core mechanical equipment in PCBA processing. The main purpose is to accurately remove the known material from the specified location through the pre-set conditions, and correctly mount it to the specified location. The placement and production capacity of PCBA processing mainly depends on the speed and accuracy of the placement machine and other functional parameters. It is also the most technical, complex and expensive equipment in the PCBA process. The automatic placement machine is a high-speed, high-precision, highly automated, and highly intelligent equipment integrating precision machinery, electric, pneumatic, optics, computers, and sensor technology. At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
