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

Does anyone know how i may get a kit for checking marking solvency mil-stand 1285b? I know 2 of the chemicals and am unsure of the other. Want to be able to perform in-house testing. sure can use some leads.

So your golden board isn't a valid representation of your production material. I don't use AOI but it sounds like either you need a vendor that can guarantee the same part marking appearance as you originally programmed to (not likely) or you need a

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 need to replace a device which is in a 6-pin package which looks like SOT 23-6 / SC-74 style. The markings are D102/ 214B (D102 above 214B). I have checked numerous references to no avail. I think that the device is a comparator or op-amp with V

I don't own a laser printer right now. I sent samples to some vendors and I couldn't read the codes. Have pictures of 2D codes on white solder mask? Thanks

On big chips, we use a tape printing device, I think it is a Brother PT1750. We have a small device, though, that is in an SO8 package, and the only thing we've come up with is to scratch a product letter code and the program date with a stylus. Th

On our machine we have found that some IC's require a different light for inspection based on the manufacturer. Have you tried other lighting options? You may need to talk to the AOI manufacturer to see if there is something the machine may be able

Every time to create new AOI program we must manual set at bright lighting level for each component. then this case we think the parameter of AOI setting it not concern for this problem due to the golden board that we use to confirm machine before st
