Top 6 PCB промышленности Тенденции и производственные проблемы, которые они представляют

ICT test, FCT test, aging test, fatigue test, and test in the harsh environment. The PCB proofing board is described as follows:

The instruction of PCB

PCB circuit board manufacturing in the following process,strict requirement to ensure your product quality and save more electronics budget

While the PCB is heated, part of the free volume of water can be dissipated through the microporous PCB substrate, thereby reducing the molar volume fraction of water that may accumulate at the voids or microcracks, which is beneficial to the explosion of the PCB. improve. However, if the surface of the PCB has a large area of copper foil pattern coverage, when the PCB is heated, the large copper foil surface above the buried hole blocks the water vapor that escapes outward after being heated, so that the pressure of water vapor in the microcrack increases, resulting in occurrence of The chance of a burst is greatly increased.

In the following, the existence of water in the PCB, the way of water vapor diffusion and the change of water vapor pressure with temperature, reveal that the existence of water vapor is the primary cause of PCB explosion.

Therefore, the soldering reliability of PCBA becomes more and more important. The followings are studied by Inspi​, and describes the shortage of the blasting plate in reflow soldering and its improvement method for your reference.

Chinese smartphone manufacturer Nubia Technology Co Ltd is bringing its innovative dual-screen technology to the flagship line of smartphones with the launch of Nubia Z20.Good news that Inpsi it also provide the service on manufacturing smart phone pcb assembly.
