SMT Industry-Intelligent Solder Paste Management System

Client：A large automobile electronic controller manufacturer

Industry：Automotive Electronics / SMT

Challenge：

The temperature recovery, use and recovery of solder paste are all recorded manually, which is easy to make mistakes and has the risk of using beyond the time limit, thus affecting the welding quality.

The failure to strictly implement the 'first-in-first-out' principle caused the solder paste to remain in the refrigerator for too long, resulting in performance degradation.

When quality issues occur, it is difficult to quickly trace the batch of solder paste used and the operator involved.

Sunntol's solution:

The deployment of the Suntone HC-400 smart solder paste management cabinet.

The whole process of solder paste from re-warming, receiving to recycling is realized by automatic management.

The system enforced the first-in-first-out rule and automatically locked the solder paste that had exceeded the usage time limit.

Each operation automatically logs personnel, time, and material data, then uploads the information to the customer's MES system via the interface.

Results and Impacts:

The efficiency of tin paste management was improved by 90%, and the time of manual recording and checking was completely eliminated.

The welding defect rate was reduced by 60% due to the solder paste.

The material traceability capability was achieved 100%, which provided a solid data foundation for quality analysis.

Customer testimonial:

"*The Sunntol smart cabinet is not just a storage device, but a key component in our automotive electronics quality system. It makes our process control transparent and reliable."
