Accelerated Test (Aging) Accelerated aging - that is, accelerated aging test (Aging). If the surface of the board is dissolved tin, sprayed with tin, or rolled with tin, how long can the solderability of the board last? The accelerated test of high temperature and high humidity can be used to simulate how the solderability deteriorates when the board ages to determine its quality. Acceptance or not.
This kind of artificial accelerated aging test, also called the environmental test, aims to see how the weather resistance of the completed circuit board (green paint) has performed. There is a new requirement in the new "Circular Board Solder Specifications" (ANSI/J-STD-003, full text version of this issue 57), that is, the PCB must be carried out for 8 hours before the Solderability test. "Steam Aging" is also such a test.
Adhesive Cleaning Cards are specially used on card printers. Card Printer Adhesive Cards can only grab dust and particles on printer rollers, they are effectless for oil, ink and glue. They are constructed by 3M original glue paper which feature strong stickiness ,heat resistant and humidity resistant. The stickiness is stronger than Card Printer Adhesive Rollers, so that they can remove the dust from Adhesive Rollers.
