How We Deliver
Solder Pasting
Solder paste is applied with high-precision stencil printers to ensure consistent pad coverage. We use only RoHS-compliant, high-reliability solder pastes. In-line SPI systems verify paste volume and alignment after every print. Environmental controls are maintained to preserve paste integrity. Stencils are cleaned and inspected regularly to prevent printing defects.
Component Placement
High-speed pick-and-place machines ensure precise and repeatable component positioning. Vision systems verify component orientation and alignment before placement. Handles a wide range of packages including 01005, BGA, and QFN. Feeder calibration is performed routinely for consistent part delivery. Placement data is optimized using CAD input to reduce cycle time and errors.
Reflow Soldering
Reflow profiles are customized per assembly to ensure optimal solder joint formation. We use multi-zone reflow ovens with precise thermal control and profiling. Nitrogen atmosphere reflow is used for sensitive assemblies to minimize oxidation. Continuous monitoring ensures uniform heating across all PCB zones. IPC-compliant inspection follows reflow to verify solder quality and joint reliability.
Conformal Coating
We apply conformal coatings to protect PCBs from moisture, dust, and chemical exposure. Automated selective coating systems ensure accurate and repeatable application. UV inspection verifies uniform coverage and absence of voids or skips. Mefron uses acrylic, silicone, and polyurethane coatings based on application needs. Curing is done under controlled conditions to ensure proper adhesion and finish.
Selective Soldering
Selective soldering is used for through-hole components on mixed-technology boards. Programmable nozzles ensure precise solder delivery to specific joints. Preheating zones help minimize thermal shock and ensure proper flux activation. We use nitrogen environments to reduce oxidation during the soldering process. Automated process control ensures consistent solder quality across batches.
