MCCB Highlights
Advantages and highlights of welding process equipment for MCCB Electronic type hardware parts
1. Acereare has strong welding core competitiveness, and uses fully automatic equipment to flexibly accept parts welding processes from all walks of life.
Various parts and components can be welded through copper loading, copper fetching, solder paste dripping, silver spot fetching, silver spot detection and positioning, silver spot welding, finished product fetching, and finished product fetching detection.
2. The key process (mass production contact) adopts fully automatic production. Dynamic and static dual vision backup detection can effectively solve the problem of reverse spot and high penetration rate level in the industry by 90%.
3. Workshop welding equipment adopts medium frequency power supply, servo motor pressurization, automatic pressure detection display and automatic defect alarm, ensuring zero defect requirements for products
