Mike, Russ is right, no 'normal' wave machine will solder PCB's with 1" long lead length. I have seen waves modified to clear up to 5/8" leads, but the deeper the wave the uglier things get. They get uglier in that a lot more dross is produced, con

Larry... I believe CCD offsets are not active on the IP3. Light levels and offsets are only availble in proper. Use Front Light. Use a P-pattern with bright lead, dark back background (I think #3)... The trick is to sample the lead width at the br

We are using a low end Air vac system to place the BGA's. We have X ray we can use. Our CGA's as well use this system. They are one off parts that are above the 20K a piece range. So I have been tasked with making sure all of these procedures are the

Challenges: The basic defects that impact assembly yield are bridging, satellite solder balls, and opens (i.e. tombstones / draw bridges). There are many variables with the stencil printing process that can impact these; several of them are listed

Hi guys; There are a few points that should be taken in to considerations regarding IPC-SM-782 land pattern and design rules. As a general rule all SMT reflow pattern should be in comply with SM-782 but however for special cases like : * PLCC land

We have a board that requires a .015 - .035" finished lead length which requires us to do mass lead trimming. To this point we've performed this activity on parts with straight leads. We're looking at going to an axial auto-insertion process (outso

It is possible to vary the length of lead during auto insert. However, it requires software and mechanical adjustments. Universal equipment allows small changes via software program for lead length. To change angle of clinch involves a mechanical a
