SuZhou Tonkida Electromechanical Technology Co., Ltd Professional SMT whole line supplier

Pickup Defects: Pickup defects can be classified as feeder failure, vacuum failure or visual failure. Picking up defects reduces net output and waste of good parts;

Second, look at the reliability/availability and maintainability of the mounter: the data on reliability/availability and maintainability are published by the supplier based on actual field experience;

Preventive maintenance: preventive and corrective maintenance to keep the SMT mounting system running at its specified speed and accuracy;

Fourth, look at the Process Capability of the placement machine (Cpk, Process Capability) : refers to X, Y and Θ related to the mounting accuracy level. The X, Y, and Θ errors of a machine are considered separately, not collectively. (Accuracy) By judging the accuracy of the SMT machine to know whether it can be affixed to all the materials that need to be affixed in the factory, it can be higher than the actual accuracy of the materials, to ensure that the pass rate of the installation meets the requirements;

Five, look at the output of the SMT machine (Throughput) : involving the measurement of transmission, manufacturing and beat time. (Speed) Calculate whether the production capacity meets the requirements of the factory production schedule by judging the speed of the SMT machine;

(6) Placement Defects: the probability of placement defects usually occur (rate of defects) by judging the placement defects of the placement machine to understand whether the finished product rate meets the requirements, thereby reducing costs and production time;

A common language: When suppliers and users use the same language to achieve a common understanding of standards and communication regarding equipment performance, the result will be increased efficiency and greater customer satisfaction and growth in the industry.
