Currently, in my working factory, we facing the flux residue remain on connector after washing. (of course, this is clean process with WS solder paste). So, are there any ways to clean the flux residue rather than go back to wash again? Because wash

Chen, It is always best to place one�s effort on determining the cause and content of the residue rather than trying to work around it. The first thing you must determine is the nature of the residue. Is it flux? In many instances, the residue is

With the explosion of growth in handheld electronics devices, manufacturers have been forced to look for ways to reinforce their assemblies against the inevitable bumps and drops that their products experience in the field. One method of reinforcement has been the utilization of underfills to "glue" certain SMDs to the PCB. Bumped SMDs attached to the PCB with a no-clean soldering process offer the unavoidable scenario of the underfill coming in contact with a flux residue. This may or may not create a reliability issue... First published in the 2012 IPC APEX EXPO technical conference proceedings

There are several industry-accepted methods for determining the reliability of flux residues after assembly. The recommended methods of test sample preparation do not always closely mimic the thermal cycle experienced by an assembly. Therefore, extraction from actual assemblies has become a popular method of process control to assess consistency of post-reflow cleanliness. Every method of post-reflow flux residue characterization will depend on the reflow process followed to prepare the coupon.This investigation will focus on the effect of thermal conditions on the remainder of active ingredients in flux residues after assembly with no-clean solder pastes.
Flux spray coating on a PCB with uniformal thickness down to 5 microns, with clear edge definition and minimal overspray. Can coat large or shoot dots with the same jet.
