ShenZhen ETON Automation Equipment Co.,LTD. Special stainless steel mesh belt: durable and wear-resistant and long life time.Įquipped temperature abnormal alarm device Independent roller structure and support and match with accompany stainless mesh belt to make the running smoothly and the speed precision is up to ☒0 mm/min. The conveyor system use STK adjustable speed motor imported from Taiwan matched with the 1:150 turbine reducer can running smooth, speed varies in 0-1200mm/min.Ģ. Vacuum vapor condensation welding (vacuum vapor phase welding) system: hollowless welding in confined space, with the highest heat transfer efficiency, 300 w-500 W/m2K.The welding process remains static without vibration.Excellent cooling effect, color has no effect on heat absorption.ġ. Gas phase reflow welding system: high heat transfer efficiency, 200-300 W/m2K, no shadow effect, welding process needs up and down movement, poor cooling effect. Hot air reflow welding equipment: high heat transfer efficiency, 10-50 W/m2K, no shadow effect, color has no effect on heat absorption. Infrared thermal radiation reflow welding equipment: the heat transfer efficiency is slow, 5-30w /m2K (the infrared radiation efficiency of different materials is different), there is shadow effect, the color of components has a great impact on heat absorption. Hot plate conduction reflow welding equipment: heat transfer efficiency is the slowest, 5-30w /m2K (heating efficiency is different for different materials), with shadow effect.
According to the continuous improvement of heat transfer efficiency and welding reliability, reflow welding can be divided into five stages.
