Hi Mark, Look on the bright side, if you want to change from HASL you've got the lead free issue which will allow you to evaluate all other finishes, and find the best one for you. Dave, have you seen any unleaded HASL finishes & any issues arising

We had a contract in house that included a flex board which required an 18 hour bake at 105 degrees. The other brds got along fine with 2 hours, but the flex board would delaminate until we went to this long bake. I don't know how the engineer came

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

Normally, you should not have to bake boards that are properly packaged and stored. Since you are seeing problems, baking makes sense. Consider 125C for 4 to 6 hours. Additionally, look here for more, while waiting for others: http://www.smtnet.

Hi, We don't have that to spare right now, but I was thinking about XP 142 and adding that to the current like, and then selling the MYDATA and getting an XP 242. Not sure about getting the CP model, as it's a serious bit of equpment, but would spee

Good day all, we have an evaporator for our PCB washer that has been fine up until recently. Everytime we run it, it boils over and makes a HUGE mess of everything. Any suggestions as to why this could be happening? Is it possible the temp controller

Clark, As a start....Do you have a qualified tech on site to verify that the camera lighting is within spec? If not it's hard to say where you are starting from. I know that UIC still has trained personel that can help you out on this older gear if y
