We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read

Hello Gav, We have tried the procedure that you described, and it didn't work well for us. Even though the viton tubing is doubled up and pinched, no amount of glue is visible at the tip of the tubing. So getting the glue to protrude from the syring

The data we have is from an IBM report. Below 100�C the SAC reliability is almost double that of SnPb (-40 to 100�C thermal cycle). When the upper end temp is increased to 125�C the reliability drops to 75% of SnPb. I'd like to see the data that s

Solder fillet inspection is something that I would avoid like SARS, solder joints are like a snowflake no two are the same, henceforth unrepeatability. The only time I would look into this would be for uBGA or flipchip on an audit basis utilizing X-

We have been processing a 3 and 5 up flex array for nearly four years on pallets and have had a pretty steep learning curve. Make sure you have vacuum holes in your pallet for the screen printing process, also work with your support block vendor to
