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

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

Piezoelectric type (office/industrial) In this method, a piezoelectric (piezo) element, whose volume is deformed when voltage is applied, is used to discharge ink particles. This element is attached to the component that is filled with ink. Then, 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

Why don't you look into a BotFactory Squink? It can deposit solder and pick-and-place. It prints conductive ink for the traces too. $3K is probably spot on for your budget. Check out http://www.botfactory.co

Asymtek in-line machine with the Jet head hands-down. And since you will be coating silicone you should virtually have no touch-up after it exits the machine because of the higher viscosity of this material.

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

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
