What Is The Role of Nitrogen in Reflow Oven?
SMT reflow oven with nitrogen (N2) is the most important role in reducing the welding surface oxidation, improve the wettability of welding, because nitrogen is a kind of inert gas, not easy to produce compounds with metal, it can also cut off the oxygen in the air and metal contact at high tempe...Read more -
How to Store PCB Board?
1. after the production and processing of PCB, vacuum packaging should be used for the first time. There should be desiccant in the vacuum packaging bag and the packaging is close, and it can not contact with water and air, so as to avoid the soldering of reflow oven and product quality affected ...Read more -
What Are The Causes of Chip Component Cacking?
In the production of PCBA SMT machine, the cracking of chip components is common in the multilayer chip capacitor (MLCC), which is mainly caused by thermal stress and mechanical stress. 1. The STRUCTURE of MLCC capacitors is very fragile. Usually, MLCC is made of multi-layer ceramic capacitors, s...Read more
