When mixed SMT and THT assemblies require selective soldering, when wave or manual soldering remains suitable, and how to select the correct DEZ machine.
Build a controlled high-mix PCBA cleaning process before conformal coating using validated chemistry, DI-water rinsing, drying and cleanliness testing.
Diagnose white residue, sticky flux films and loose solder balls on PCBAs, then select the correct soldering correction, test and cleaning process.
Compare brush, ionised air, vacuum and tacky rollers for removing particles from bare PCBs and accessible post-solder PCBA surfaces.
How ionic contamination differs from visible PCB residue, what causes electrical risk, how cleanliness is tested and which cleaning process fits.
Learn how PCB surface particles cause solder paste smearing, bridging and insufficient deposits, and how to verify the root cause before reflow.
Learn how PCB cleaning machines remove dust, flux residue and ionic contamination, and compare dry, brush, batch and inline cleaning equipment.
what causes flux residue on PCB assemblies, when cleaning is required, how to select a cleaning process and how to verify cleanliness.
Send your PCB or workpiece dimensions, current production problem, required throughput and available factory utilities.
For cleaning projects, include the contamination and required cleaning result. For selective soldering projects, include the PCB drawing, THT solder-joint positions, solder alloy and flux information.
