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

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

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

Hi.Thanks for reply. 1. - I guess after JETting the paste, the head will go aside, to allow head with HD camera(SPI) to do the job.....and thus if used for AOI , the same camera will be much higher above components, not damaging anything....this is

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
