Where can I do secondary screening for components? Professional organization answers

Date:2024-04-25 11:36:01

Where can I do secondary screening for components? Secondary screening of components is a qualification inspection conducted before the installation and use of components, with the aim of eliminating early failed products and improving the reliability of product batch use. After the acceptance of the components is qualified, the ordering unit or the user unit shall entrust the component testing station to conduct secondary screening according to relevant regulations, and it is required to remove early failed components. Secondary screening of components is a supplement to primary screening, and should comprehensively consider the usage conditions and application environment of components based on the items and stress of primary screening.

Reasons and solutions for defects in reflow soldering and wave soldering

Date:2024-04-24 10:40:54

There are several different methods for reflow soldering, including wave soldering and gas-phase reflow soldering. Wave soldering is the process of moving a PCB through a solder wave to cover the solder pads on the PCB, and then placing the mounted components onto the solder. Gas phase reflow soldering involves placing the PCB and mounting components in a heated furnace to melt the solder and solder the components onto the PCB. This article has collected and organized some materials, hoping to have significant reference value for readers. View >>
