Frequently Asked Questions

Can this inline selective wave solder machine handle dual solder pots?

Yes, the I.C.T-SS550 supports both single and dual solder pot configurations. Dual pots allow operators to run different alloys or boards simultaneously, increasing throughput and reducing changeover time. For multi-device SMT or DIP lines, this flexibility ensures continuous production without compromising solder quality. Adjustable flux and wave parameters can be programmed for each pot, maintaining consistent solder joints across high-mix production scenarios in automotive, industrial, or consumer electronics applications.
What is the best selective soldering machine for large PCBs?

The I.C.T-SS550 can handle boards up to 500×500 mm, making it suitable for large PCB applications. Its precision transport system and XY positioning ensure uniform solder coverage, even on heavy or multilayer boards. For high-volume or prototype runs, operators can adjust the machine’s wave height, preheat zones, and flux application to maintain joint quality. This makes it ideal for automotive, telecom, and industrial electronics where large PCBs are common.
How does nitrogen improve soldering quality?

Nitrogen significantly reduces oxidation during selective wave soldering, promoting better wetting and minimizing dross formation. With 99.999% purity at a controlled flow rate, the I.C.T-SS550 prevents defects such as bridging or uneven solder joints. Operators can integrate nitrogen monitoring with MES dashboards for multi-device production lines, ensuring optimal solder conditions. This improves yield, reduces rework, and extends the life of solder pots in both small-batch and high-volume operations.
