How to Avoid PCB Soldering Defects? 1. The solderability of the pcb circuit board holes affects the soldering quality The poor solderability of the circuit board holes will cause virtual welding defects, affecting the parameters of the components in the circuit, resulting in unstable conduction of the components and inner layers of the multi-layer board,…
The screen printing layer of the PCB board is the text layer. Its function is to facilitate the installation and maintenance of the circuit, and print the required logo patterns and text codes on the upper and lower surfaces of the high density pcb, such as component labels and nominal values, component shapes and manufacturer…
When customers customize PCB products, they will produce more in quantity to prepare for they pcb projects. Over time, the PCB board will expire. So, what are the hazards of using expired PCB circuit boards? 1. Expired PCB fabrication may cause oxidation of surface pads Oxidation of the solder pad will cause poor soldering, which…
We know that in high-speed PCB design, seemingly simple hole often bring great negative effects to circuit board design. Therefore, in the design, we should try our best to do the following: 1. Considering both cost and signal quality, choose a reasonable holes size. For example, for the 6-10 layer memory module PCB design, the…
