Borey Advanced ASMPT's Process Lens makes outstanding contributions to testing

2025-07-17

ASMPT's Process Lens system plays an important role in the solder paste printing process, and according to statistics, this process is the link that causes the most abnormalities. Its SPI system can even identify the smallest deviations and trends. The DLP chip is equipped with up to 20 million individually controllable micro mirrors, which can inspect the volume, height, substrate area, shape, and position of each solder pad. This device can detect relevant areas on the PCB through two-dimensional scanning, and then perform 3D stereoscopic measurement. Its operating speed is 70% faster than traditional devices. The resolution of Process Lens is as high as 10 μ m, and the false alarm rate has been reduced by 80%.

The excellent performance of this device also leaves more time for other additional measurement tasks, while not prolonging the unit detection time, such as detecting foreign objects or checking glue points. Another advantage of this device is that Process Lens HD is one of the few SPI systems on the market that can control measurement resolution through software.

Automatic optimization of printing process

Under the collaborative action of ASMPT's Process Lens or third-party SPI system, the printing process can achieve fully automated operation without the need for operator intervention. When needed, the system can also trigger automatic offset correction or cleaning cycles. Through virtual printing based on steel mesh data and ASMPT's rich process database, the printing module can determine all relevant printing and process parameters, mark key areas in the steel mesh layout, and provide improvement suggestions before printing the first circuit board. With the help of "partial factor analysis experiments", the speed of new product launch is faster because only a few targeted test prints are needed, and the software can calculate all the parameters for optimizing steel mesh printing in a few minutes, making the entire process more stable.
