1. Precision Flux Spray System
Selective spray technology reduces flux consumption by ≥90% vs traditional methods.
Ultra-narrow 2mm spray width minimizes ionic contamination (eliminates post-soldering PCB cleaning).
Dual-axis servo motor ensures ±0.02mm positioning accuracy.
Contamination levels meet IPC-J-STD-001 Class 3 standards.

Hybrid heating system for leaded/lead-free/multilayer PCB assembly:
▸Bottom heating: Short-wave infrared technology
▸Top heating: Forced hot-air convection
Integrated preheating stations for each soldering module
Programmable per-joint parameters:
▸Differential soldering speeds
▸Custom dwell times (0.01-10s adjustable)
EM Pump Technology™ features:
