For producers of digital printed-circuit–board assemblies (PCBAs) that help finish merchandise in infrastructure, medical, aerospace, and different industries, tolerating even the slightest defect is just not an choice. These corporations should due to this fact make investments closely in essentially the most superior, dependable, and environment friendly high quality management programs that the automation trade can supply. To handle these challenges, Worthington Meeting embarked upon an intensive undertaking to establish and workforce up with the correct know-how and options accomplice for its inspection wants.
Worthington Meeting wanted a brand new partnership that might assist it discover the correct inspection capabilities to check merchandise, enhance high quality, and higher perceive processes. The South Deerfield, Massachusetts–primarily based firm had reached a tipping level within the technique of increasing its enterprise and buyer base. So as to meet rising demand whereas sustaining high quality requirements, it wanted to put money into extra succesful 3D automated optical inspection (AOI) tools. An extra problem was incorporating 3D solder paste inspection (SPI) tools into the method for the primary time.
Actual-world challenges
Worthington Meeting, based in 1974, is thought for delivering high-quality merchandise, together with PCBAs. The corporate prides itself on quick turnaround occasions for small-volume prototype and manufacturing runs of extremely advanced designs.
As the corporate has enhanced its functionality from dealing with easy work to accommodate difficult buyer calls for, Worthington Meeting has achieved speedy enterprise development. Together with that development, the agency confronted frequent problems with discovering, hiring, and coaching extremely expert inspectors to assist preserve a quick and efficient inspection course of.
The agency had been utilizing a 2D AOI machine, which was incapable of assembly its manufacturing and inspection wants. Like many producers, Worthington Meeting additionally had challenges with some tools suppliers, together with a scarcity of innovation, damaged guarantees, poor communication, and unreliable engineering help. Worthington Meeting wanted to keep away from a repeat of those experiences and overcome roadblocks.
Choosing a brand new inspection-solution accomplice concerned weighing not solely know-how and capabilities but additionally help groups. Worthington Meeting wanted help from educated consultants to beat rising pains as a result of studying curve related to introducing new know-how.
Worthington Meeting selected industrial automation options supplier Omron Automation Americas—for 3D SPI and 3D AOI.
Adopting new tech, step-by-step
Worthington Meeting acknowledged that its current 2D AOI know-how had extreme inspection limitations, resembling a scarcity of any actual skill to catch potential defects on essential ball-grid–array units. The agency was relying utterly on inspectors to catch defects—resulting in the discharge of some faulty merchandise.
3D SPI is good know-how to forestall such incidents.
Worthington Meeting applied the Omron VP5200-V 3D SPI system first, because it was seen as a neater, lower-risk utility for the aim of evaluating the inspection accomplice’s know-how and tradition.
Preliminary outcomes that demonstrated the ROI of the SPI system have been glorious, and Worthington Meeting might inform straight away that the forms of defects that they had skilled post-reflow have been now not associated to their stencil printing operation.
Worthington Meeting then took on the 3D AOI undertaking.
Omron 3D AOI is designed to enhance inspection functionality and efficiency stability versus legacy 2D and color-based programs. It enhances defect detection of inauspicious points like solder wetting, lifted lead, and element coplanarity whereas amassing worthwhile measurement and picture knowledge to additional enhance the method and forestall defects from reoccurring. Making use of a 3D-based, IPC-correlated method to element and solder joint inspection with quantifiable measurement thresholds is the most effective means to enhance the standard assurance and course of management of assembled PCBs.
Omron applied the VT-S730 3D AOI system to handle Worthington Meeting’s post-reflow inspection necessities. The VT-S730 integrates Omron’s superior 3D color-highlight illumination with true 3D, DLP imaging know-how 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 complicated inspection capabilities make sure that merchandise are constructed to high-quality requirements and carry out as designed.
Worthington Meeting’s analysis course of included working each product via the brand new 3D AOI, current 2D AOI, and a guide QC course of to find out effectiveness. After many weeks of placing the VT-S730 to check, not a single defect escape was recognized.
Worthington Meeting then launched and educated a second programmer, who was in a position to obtain the identical outcomes and with none impression to effectiveness.
A lift for high quality and coaching
Worthington Meeting has successfully decreased post-reflow defects by incorporating 3D SPI to enhance and stabilize the print course of and make sure that any print points have been as a result of human error and never the automated printing course of. The producer is constant with its desired inner technique of 100% 3D AOI inspection with occasional QC sampling. With an understanding of the right way to efficiently make the most of 3D AOI, Worthington Meeting has gained confidence in its new know-how, inspection course of, and the standard of its deliverable product.
3D SPI additionally considerably improved the time it takes to coach new personnel on printing boards. Beforehand, they wanted to show workers the right way to each print and examine boards, however now they solely want to point out them the right way to load applications and let the machines automate the remainder of the method.
