I am looking at putting a laser or ink jet marking system for barcoding of pcb's in our smt production area. As and inline system it will need the capability to handle different size boards. We use dark green pcb's except for couple red and blues m

Barcode needs a light colour backgroup so that the scanner can read. No way you can mark on the solder mask and become readable. I found most of the time the investment cannot be paid back within 5 years. Most of the time it is product requirement th

The alternatives are ink-jet and laser and you'll spend way over $20,000 for that solution! Screen printing is still the best at ROI when doing multiple panels and lot's of legends. We used a rubber stamp inked with Hysol for smaller quantities and o

All: I am interested in how process engineers are both removing and adding markings to active devices. We have a job where we have to both remove the markings of and the re-mark SOICs. The markings on the devices look like they are pad or ink jet p

Hello Michael, Laser marking and ink jet marking are now offered by a wide array of suppliers. The was a bit of a boom at APEX last year in the number of suppliers for these systems. Many have tried label placing but have run into a number of conc

I manufacture industrial ink jet printers. I have a new application to join an unpopulated flex circuit to a light ly populated PCB. Production requirements are rather low. The area To join is 300 solder balls on the flex occupying an area of 5/8 i

Rick, I think Autosplice and Berg did that but of course, it was a little before my time. But the comparison is the same as what HP does with injet printers and the ink cartridges which for some reason made me think of a screen printer someone made t

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
