Koh Young Drives Qualitel’s Operational Improvement Continued from previous page
And that wasn’t all that was on the
shopping list. Qualitel was looking for a so- lution that was easy to use and fast to pro- gram, plus it had to be accurate and reliable with a very low false call rate. It also need- ed to connect to the company’s AEGIS SPC traceability system. “Koh Young’s initial presentation was
very clear and detailed; highlighting all the capabilities, ease of use in programming and functionality that we felt it was only right to add them to our assessment,” says Hoa Hoang, Qualitel’s vice president of op- erations. “They also invited our team to their demonstration facility to walk through an evaluation run. After a short time period, this was an easy decision to en- gage in contract negotiation and scrap our current supplier that we were evaluating in-house... Koh Young’s capabilities far ex- ceeded the competitors, and we are very happy with our deci- sion.”
Qualitel selected Koh Young
for many reasons, from its world- wide presence and reputation for continuous improvement, the ac- curacy of its data, the ease and speed of machine programming, to its conversion support and simplified images and data. Qualitel started with two
SPI machines and four AOI ma- chines. Koh Young’s technical support was onsite to train Qualitel engineers and support the machine handover. As with any change, the operators were initially hesitant, but after the machines proved their speed and dramatically reduced false calls, there was a complete mind shift. They quickly accepted and adapted to the new machines.
Performance Improvements After a short while running
the machines, Qualitel realized immediate benefits, including: 95% reduction in false calls; re- duced production time by 2.5 minutes per assembly; and a 75% reduction in programming time. It also upgraded inspection pa- rameters, such as: IPC-A-610- based joint measurement; lifted leads and parts; FOD (Foreign Object Debris); and component lead and body coplanarity. This results in reduced prod-
uct rework, improved first pass yield quality, a 50% DPMO im- provement, dramatically im- proved downstream test yield to over 98%, improved solder paste print accuracy with new inline 3D SPI inspection technology, and simplified data collection ef- fort to monitor and control process limits. Qualitel’s journey and part-
nership with Koh Young contin- ues as they explore automated optical inspection in post-SMT processes. Qualitel has been sat- isfied and impressed with the se- lection of Koh Young. The compa- ny has become a trusted partner. “Koh Young is a trusted, ex-

tremely responsive partner of Qualitel. We look to them for assistance in multiple ar- eas, including process questions, applica- tion support, and software updates. We reach out to Koh Young whenever we need technical support, and they are there for us,” concludes Hoang. “We added Koh Young at a time when we needed to triple our output. They fully supported our imple- mentation, without which would have stalled our rapid growth. Koh Young is es- sential to Qualitel and we would confident- ly recommend them to anyone.” Contact: Koh Young, 1950 Evergreen
