I agree. The bar coded label you use should not be affected by the solder mask of the board. The label should have sharp contrast between the segments of the code to modulate the returned light and allow the reader to discriminate between light and

We've been using pre-printed labels on our PCB's for years, with 8 - 10 hours a week down time associated with them. Last October we put a CO2 laser marker on one of our lines. In 6 months we've had a total of 30 minutes down time. We use a 2D b

I always have a difficult time with seeing people using two different manufacturers products. Here your printing with Senju and hand soldering with Kester. So if theres a problem you have to look at two different products, contact two different compa

My experience with different size boards and pre-heaters. The perfect world (right?) you would saturate the complete pcb with bottom pre-heat. But it is difficult with repair and rework equipment, not to mention the expense and foot print of large pr

Ashok: Well, your customer probably has a good reason for wanting you to send them boards without holes in the solder mask. What is their goal for the mask capabilities after you get do reworking the boards? * Cosmetic surface coat? * Performance t

1. The jetting head flies very low to the level of the board. So, performing AOI function will crash the head. 2. AOI is performed close to the end of the line, after P&P or reflow. Are you planning to run the boards back-and-forth, on the line? 3. L

Semiconductor fab back-ends and production contractors use laser assisted solder jetting for protoyping, repair, and other low volume flip chip bumping. * As you say, printing paste is going to be very tough to control. * Solid ball placement is ai
