I.C.T Engineers Inspect Online Selective Wave Soldering Machine

I.C.T has completed an on-site inspection of an online selective wave soldering machine, checking machine condition, process parameters and solder joint quality before the equipment continues in regular production. The findings were documented and handed to the customer together with the corrected settings.

Selective wave soldering handles the through-hole and mixed-technology joints that reflow cannot reach. The process depends on a small solder pot, a nozzle, flux deposition and preheat all working together inside a short cycle, so a machine that drifts quietly still produces joints that look acceptable on the bench and fail later in the field.

The inspection covered the wear items and the process in one pass: solder pot and nozzle condition, solder level and alloy, flux spray pattern and volume, preheat profile, conveyor parallelism and board clamping, plus a review of the soldering programs against the customer's boards. Sample boards were then run through the online selective wave soldering machine and the joints checked for fill and bridging, with parameters corrected wherever they had moved away from the recorded baseline.

Only minor corrections were needed, and the machine is back in normal operation. The customer's team was briefed on the daily checks that catch drift early — nozzle condition, flux delivery and solder level — so small deviations are picked up at the machine instead of at final inspection.

Preventive inspection is part of I.C.T's after-sales support for installed equipment. For selective soldering, where a single nozzle carries a large share of the process risk, a scheduled check is usually cheaper than the rework it prevents.
