Large series of lead-free reflow soldering

The world's leading micro-circulation heating method can achieve large air exchange rate, has a high heat exchange rate, can reduce the temperature setting temperature, and protect the heated components, especially for lead-free soldering.
Leading micro-circulation heating method, vertical blowing vertical wind, can solve the problem of dead angle in general reflow soldering using rail welding.
Leading micro-circulation heating method, the air outlet is closest to the air outlet, which can effectively prevent the influence of wind flow when the PCB board is heated, and achieve the highest repeated heating.
Ensure the ultra-stability of the heating process, and have the industry's smallest Δt deviation, especially for difficult welding processes.
The rapid cooling system from international technology adopts amplified centralized high-efficiency quenching, and the cooling speed can reach 3.5~6°C/sec. The management is very convenient.
Five-wire guide rail transmission mechanism ensures accurate and high service life of the guide rail.
The computer controls the automatic lubrication system, which can set the refueling time and fuel quantity through the computer to automatically lubricate the transmission chain.
Integrated control window, computer switch electric adjustment, measurement curve, print curve and transmission data can be easily operated, and the design is user-friendly.
The curve test and analysis function can analyze the highest temperature, interval time, temperature rise and temperature drop speed, and facilitate process adjustment.
The operating system with password management prevents unrelated personnel from changing the process parameters, and the operation record management can trace the process of changing the process parameters to facilitate the improvement of management.
The cycle speed is continuously adjustable to deal with various welding processes.
Rosin recycling system, rosin directional flow to the storage bottle, replacement and cleaning is very convenient. Use stainless steel pipe to transport waste gas, free maintenance for life.
With a high heat exchange rate, the temperature difference Δt generated between the BGA bottom and the PCB board is extremely small, which is in line with the strict requirements of the lead-free process, especially for lead-free products with high difficulty welding requirements.
Windows Windows operation interface, dual control system, optional system, provides two modes of computer control and emergency manual control, with double guarantee function.
