Good Morning, I have been struggling with this part for some time now. I have to agree that whoever designed this part, did not have to manufacture with it. We have advanced to a point where they have a acceptable yield but I believe that will be hi

Maybe the problem is not the cutter, but the arm that advance the tape in the adjacent feeder gets actuated at the same time as the active feeder. line-up a feeder in pickup position visually, then turn the crank until the roller or feeder advance me

One shop picked up productivity with walkmen. The hand assemblers were jammed in tight and frequently face to face. It cut down conversation significantly and reduced complaints about music in general. The policy was eventually changed to only one he

What problems are the quality people seeing? I hope they aren't expecting a toe fillet. QFNs are typically cut from an array after plating. This leaves exposed copper on the sides of the part. We'll often see smearing from the sawing process that

Casimir, The Q and other lead trimmers work extremely well if properly used. Blade life is directly proportional to to the height of the cut. There are a few factors that are very important in trimming. You are working with a solid carbide blade whi

I saw another thread about kapton stencils for rework. I didn't want to hijack that topic, so I am starting a new one. I while back I had the idea to cut KAPTON stencils with a CRICUT machine. I was going to run a test, but I couldn't get a clean

Depending on the connector you should be able to use a standard cheap arbor press with some cheap home-made tooling. Standard arbor presses typically have a rotating disc with cut-outs, remove this and put a decent quality stainless steel block in it

A little more detail on our application: It is a large fixture (approx. 15" x 18") that spans the chain fingers in the reflow. It has several cut-outs and reductions in thickness to allow for better heat distribution. It worked well/stayed flat fo
