We place a similar square pin style of connector on one of our products. The connector is a 22mm high HW series from Samtek. We have a Yamaha YVL88 MK1 and YV88XS set up to handle them (Yes they are rebadged as Philips machines in some markets). No

Based on a previous question, I'm interested in learning about some of the strengths/weaknesses of machines in the pick and place industry. I'm not looking to buy a machine so I'd appreciate it if the reps would stay out of it, I want to hear from t

Tks BT Can't be many places tougher than automotive, 'cept maybe oil field, down pipe. We use Dexter Hysol flow underfills for both 1 thou and 3 thou gaps, but they wouldn't come close to filling under a BGA. Most BGA are sitting about 16+ thou fr
