Hi Mark, There are many tools available for measuring solder paste height. Most machines use laser as the basis for inspection while others use structured white light. If simple height and width inspection is all that is required, you can look int

Is this a manual measurement machine? As already stated, knowing the height of the pad underneath the paste brick is critical to knowing the true height an/or volume of paste. Any decent automated inspection system will have a way to factor out the p

Hi ! The main problem being faced currently is formation of solder balls - to be precise, these are micro solder beads generally found attached with bodies of SOTs, Chip Caps, Chip Resistors, between pins of SOICs (50 mil) - lying on PCB surface,

Let me put my two cents into this argument..After being part of many extensive studies conducted to determine the benefits of solder paste inspection, there has never been a case where the customer concluded that paste inspection (Height or Volume)wa

There are many low cost paste inspection systems on the market today. It really depends upon your overall needs for process improvement. The CyberOptics LSM series of inspection devices use a single laser stripe to calculate both Height, Area and V
