Provided that WAi would in all probability be experiencing some rising pains because of the studying curve related to introducing new expertise, having help from educated specialists was essential to its continued success in a extremely aggressive business.
WAi turned to industrial automation options supplier Omron Automation Americas for each 3D SPI and 3D AOI. Omron shared WAi’s dedication to high quality whereas offering the perfect all-around worth comprising ease of use for tools and software program, distinctive inspection functionality, glorious cost-competitiveness, and professionalism as a provider.
A radical analysis course of for state-of-the-art inspection options
WAi acknowledged that its present 2D AOI expertise had extreme inspection limitations comparable to a scarcity of any actual skill to catch potential defects on essential BGA units. The inspection course of has turn into labor intense since they had been 100% counting on inspectors to catch defects. When operators did not catch defects, faulty merchandise had been being launched and a buyer would expertise intermittent failures.
3D SPI is good expertise to stop this sort of incident from occurring. WAi applied the Omron VP5200-V 3D SPI system first, because it was seen as a better, lower-risk utility for the aim of evaluating the inspection companion’s expertise and tradition. The producer paid nice consideration to Omron’s ease of use and provider capabilities.
WAi was happy with Omron’s data and competency, particularly with respect to figuring out easy methods to efficiently implement new inspection expertise into present operations. Preliminary outcomes that demonstrated the ROI of the SPI system had been glorious, and WAi might inform immediately that the varieties of defects that they had skilled post-reflow had been now not associated to their stencil printing operation. The corporate was additionally very impressed with how fast and simple it was to study and use 3D SPI. The success of the SPI machine was readily obvious, and WAi was emboldened to proceed with the 3D AOI mission.
Omron 3D AOI is particularly designed to enhance inspection functionality and efficiency stability versus legacy 2D and colored-based techniques. It enhances defect detection of adverse points like solder wetting, lifted lead and part coplanarity whereas amassing helpful measurement and picture knowledge to additional enhance the method and forestall defects from reoccurring. Making use of a 3D-based, IPC-correlated strategy to part and solder joint inspection with quantifiable measurement thresholds is the perfect means to enhance the standard assurance and course of management of assembled PCBs.
Omron applied the VT-S730 3D AOI system to handle WAi’s post-reflow inspection necessities. The VT-S730 integrates Omron’s superior 3D Coloration-Spotlight™ illumination with true 3D, DLP imaging expertise and 5 optical cameras to realize 100% inspection protection of each half and each solder joint. Omron {hardware} delivers dependable operation and Omron’s distinctive and complex inspection capabilities ensures merchandise are constructed to prime quality requirements and carry out as designed.
WAi’s analysis course of included operating each product by way of the brand new 3D AOI, present 2D AOI and a guide QC course of to find out effectiveness.
