I would highly recommend Assembleon OpalXII/TopazXII for your low volume high mix applications. You could perform changeovers very quickly. Of course it depends on how many feeders are required per product. If you buy for example, 2 OpalXII machines

Stefan, The scenario you describe is the way it is done on our 3 series placement machines. The C5 series is a databased arrangement. Each reel (tube and tray) that comes in the door gets a unique ID (and a barcode label). This is done with the C5

Have you got some experience with using laser (CO2 or fiber one) to label with barcode your PCBs ? So far I thought it is easy process but now we do tests with many PCBs covered with diffrent soldermasks and fiber laser as well as CO2 has same probl

In a previous life we burned bar-codes on PCB with a CO2 laser. Initially we placed a small white epoxy pad to burn the code into. After some experimentation we found that we could eliminate the epoxy and just burn through the soldermask and the un

Panasonic has a great training facility in Kentucky that could be of enormous benefit to you and your team. Materials and Lasers range in capability. Generally speaking you need good contrast; which is not always guaranteed with bare PCBs. As othe

Hello, we mark our PCBs with a data matrix code using an INSIGNUM Laser 4000 from ASYS. This DMC is read at each machine for traceability. Also on our Fuji AIMEX IIIc pick-and-place machines. Unfortunately, we always have problems with the recognit

In this case a marking of some kind that clearly distinguishes between those different parts is essential. Different stocknumber for example will do and can only be trusted if measurements like in this case do not give 100% clearness. If you have the

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

| You can prepare your setup off line, using additional tables, and exchange very fast just sending the new program and checking using a barcode reader. Also you can edit a setup program with mixed feeders between PCB families. You can decrease your
