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 Volume. The volume measurement is accomplished by drawing a template around the solder pad to estimate the area. This value is then multiplied by the cross sectional height data and.."Volume" is generated. It is a very basic way of providing a window of acceptable values. The LSM 300 (AutoLSM) does provide added benifit through its use of the "Auto Feature" finding software. This will help eliminate the errors found from operator to operator variations in measurments. The the entire line of LSM systems can be supported by LaserVison Technologies. We have over 10 years of experience selling and supporting the pre-owned equipment of CyberOptics.

The ASC International SP3D provides the same level of output as the LSM 300, but is typically priced much lower on a retail basis. From a price to performance standpoint, the SP3D simply provides more bang for the buck.
ASC International also supplies the VisionMaster line of products that provides a much higher level of inspection capability. Using structured white light as its technology, VisionMaster provides true 3D, true volumetric values. This technology is typically found only on machines in exceess of $100,000. The only drawback is pricing from which the VisionMaster starts out at $24,995. A much higher investment then the other devices on the market, but does provide the capabilities to take inspect micro sized deposits such as the 0201's. Demo or pre-owned VisionMaster systems can be found from time to time priced anywhere from $10,000-$20,000 depending upon the source and warranties offered.

Beyond these two companies, there are a few others dabbling in the market with variations more suitable for general metrology needs. The Focus-refocus methods rely soley on each individual operator to determine values. Accuracy on these machine can be suitable, but operator dependance is almost always the norm. A search of the internet will yeild many options to consider. It is best to determine your overall goal both current and future and make your decision from there.
The information I am providing is very much related to my experience from a sales side. LaserVision Technologies provide sales, service and support of all makes and models of pre-owned solder paste inspection systems. It is not our goal to force one specific product towards a customer, but to allow the customer to choose which machine is the "best fit" for their process control strategy.

Good luck in your search.
Thank you.
