KAYA-Y250BE

The KEYAN-Y series BE wave soldering machines with dual-zone preheating are Keyan's entry-level equipment for small-batch to medium-scale lead-free through-hole PCB soldering. The dual-zone infrared/hot-air preheating system operates from room temperature~230°C with an accuracy of ±5°C, activating flux and preheating PCBs to reduce thermal shock during soldering and improve soldering quality. The soldering system uses a patented clog-free nozzle/ST-6 nozzle together with an ST-6 lumina atomizing nozzle for fine, uniform flux application. Flux flow is adjustable from 10~100mL/min and needle valve pressure from 0.2MPa~0.5MPa. Pneumatic full-board spraying is standard and selective spraying is optional. The corrosion-resistant, durable solder pot is made of 316 stainless steel+cast iron+titanium, with model-dependent capacities of 150kg to 280kg and a maximum allowable temperature of 300°C. Wave height uses stepless variable-frequency speed control, adjustable over 0~15mm as standard or 15~20mm as an option to accommodate different board thicknesses and component heights. The conveyor uses single-hook/double-hook titanium fingers as standard, with optional heavy-duty double-hook fingers for PCBs of different weights and sizes. The touch screen+PLC (HMI+PLC) control architecture is easy to operate and maintain. Cooling uses forced air, with a required exhaust flow of 15m³/min ×2 channels and exhaust outlet diameter of Φ200mm. Typical small-batch through-hole soldering applications include consumer electronics power supply boards, small appliance control boards, LED lighting driver boards and industrial sensor modules.
