Surely somewhere the cleaning or rinsing liquid gets to the other chamber. It is possible that the chemical migrates to the flush or flushes the chemical into the chamber. I have had a similar situation, high foam, injection vertical spray offline st

0603's and 0402's are being damaged by the water wash post reflow. PCA's are 1" X 4" and 2" X 2" approximately. We've adjusted water pressure so that the top-down is higher than the bottom up. The baskets have a .5" mesh spacing. Some baskets h

We are manufacturing an NPI board for a Customer and they want us to wash the board using a Saponifier wash. However, one of the SMT parts cannot be placed through a wash process. Has anyone ever had to encapsulate a component to prevent water da

Hi Michelle, Due to the dense population of through hole on some boards, after a 35 minute wash, some connectors or battery holders remain wet. Currently we put them into drying ovens at 70c for a Minimum of a half hour. We do occasionally air dry un
