Finetech to Demo Contactless Residual Solder Removal at IPC APEX 2019
Using innovative new technology developed by our Martin subsidiary, the SMART DESOLDER 01 combines a manual hot-gas source with a vacuum pen for non-contact extraction of residual solder. This process-controlled method has advantages over the hand wick (braid) technique by effortlessly removing components without applying and re-applying uncontrolled heat and pressure to the PCB over and over.
Damage to the pads from overheating or mechanical stress is avoided through targeted convection heating of the residual solder after component removal. The temperature-controlled airflow prevents the neighboring components from heating up. After melting, the residual solder is removed – without contact – using a vacuum pen. The Teflon tip in the vacuum pen offers a nonstick effect, temperature-resistance, and a soft surface material with a long shelf life.
As a compact, stand-alone device, it virtually fits on any workbench and can be easily operated for practically any surface mount device. Martin also provides bottom heaters HOTBEAM 04 or 05 – a perfect complement the SMART DESOLDER 01. These HOTBEAMS optimize the temperature curve by means of a sensor-based or programmed preheating profile.
