Frank, We are currently running lead free for approximately 1 yr. now but no where near the volumes you have mentioned. We are about 5k units per month. I personally am in agreement with you as far as OSP. I also do not like white tin finish since

Hi, Thank you for your answers. But I want to explain some points on which I would appreciate any comment: * Having calibrated the process, we intend to carry out the ROSE test just on SAMPLES of the finished boards. Lets say one every hour. I exp

A little late to the party here, sorry... Has the joint been verified as a cold solder joint? That is, visually confirmed that it looks like cold solder, and, perhaps, xrayed to confirm the solder status? X-raying may sound a bit extreme, but you'

We actually ran production boards on Mydata and Universal Advantis. The Mydata machines software was very command line oriented which I thought was strange but they said they had no intention of upgrading it. The Mydata placement accuracy was superb.

Greetings everyone. We are currently doing some experimentation with solder paste printing over ground planes. In this application, the entire perimeter of the PCB is a ground plane. It's about 4mm wide and wraps around the whole PCB; There is no so

OK, here we are: 1. OS is OS&2 2. Sw. is USOS V1.14 3. GSM1 4. 2 Flex2 heads 5. Problem is on the front head 6. No 7. No 8. It just stops in the middle of the placement phase, with the head over PCB area. Usually 2 parts are still held on the nozz

Dstadem, Thanks for bringing your in valuable experience with the J STD 005 " Requirements of Solder Paste". I fully agree with you that the Solder Paste can be qualified for shelf life by doing simple viscosity test and visual inspection for coal
