Hello All, Can someone direct me to businesses that will come to your place of work and certifify your operators in lead free soldering for Class 2 electronic circuit boards. Thanks in advance, Kathy

Another source for hand-on training as well a sCD-based training for l-f processes is BEST at http://www.solder.net

Unfortunately, IPC-D-279, IPC-TM-650, IPC-TR-464, and MIL-STD-810 will not answer your questions, because they do NOT address LF-solders. Even the tests in IPC-9701 need to be modified for LF-solders, because: * LF-solder has different creep behavior

Hi Nemo, In my factory we have an offline AOI from VISCOM for two SMT lines. It's not so easy to program, but the results are very good. Anyway you should have to think that an AOI system needs a human inspector and a technician to debug the program

Solder spattering, solder balls, components "popping" off pads........ Not a serious chemical reaction, however, as replied to by KEN on 12/21/04 in a similar article: "Are you adding liquid flux? Or paste "Gel" flux? If liquid flux: This, in my m

Are you adding liquid flux? Or paste "Gel" flux? If liquid flux: This, in my mind, is an unacceptable technique. Why? 1. Can not control metals content. 2. Probably not adding the same chemestry flux...as paste flux has many different addi

We had the data at the time and it was quite high. More false calls then anything. I do not have the data anymore it since has been archived. When the system was introduced we had 1 engineer and 2 operators trained for programming and running the

I'm currently working for a OEM that has 700+ stencils in house and we received 30 to 40 stencil a month. We recently switched to a no clean process which is causing the stencil part numbers to disappear from the stencil frames due to the saponifier

We have this problem for a long time. It happens to 3 new Mydata MY-9 machine. When pick and place resistor array 0408 (different value, top and bottom side), the solder paste in the middle two terminals missing occasionally. Thought it's because noz
