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

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

Hi everyone, I've been out of it for a while after 27 years. Got made redundant in February. What can you do? I know - turn 60 and get cranky. That'll be the ticket. Anyway...... Trying to help someone out with a Yamaha YVL88MKII. I am very conversa

Hi Luis A white mask typically helps in the marking process since you are not reliant upon the PCB layers to create the contrast. Laser marking is really an etching process, so if your laser is set properly (power and focus) the goal with mask is to

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

2D codes take up much less real estate so that might work. Something else we did was to go to CO2 lasers and mark directly into the solder mask. Underlying copper gave adequate contrast to the green mask. Much more of an investment, but works grea

| We are looking at implimenting a bar code system for a SMT | production line. To start we are looking at label printer/applicators. Are there any other companies that we should consider besides Zebra and Imtec?? Thanks for your input. | John If

We are looking to barcode our pcbs for industry 4.0 traceability. We have a fairly new laser that we use for other operations like case marking and would like to use this to mark a 2D barcode on the PCB surface for the SMT equipment to be able to s
