PCB circuit board cleaning effect detection is PCB production, processing and circuit board to board design and other aspects of the system board are involved, the method cleaning effect on the PCB testing and evaluation criteria , electronic processing and circuit board engineers should follow certain standard.
1. raw material quality requirements

2. The printed circuit board cleaning quality requirements

At present, China's electronic industry as the final product quality cleaning printed circuit board has not yet formed a unified specification.PCB circuit board


二，Detection method

1. visual inspection without using a magnifying glass , a printed circuit board surface direct observation with the eyes should be no visible residue exists.

2. Surface ionic contamination test method. PCB circuit board

1 ) extraction solution resistivity (ROSE) test method principle extraction solution resistivity law to 75% isopropyl alcohol plus 25% deionized water ( volume ratio) of the test solution , rinsing the surface of the printed wiring board and the residue contaminants on the surface of the printed circuit board is dissolved into the test solution . 2）Calculate 3)Relationship 4)Calculate.
