Mark: One thing you will find with the Panasonic software is that it will use one component file for the same size/shape component. This is a good starting point. However, you may have better succes changing the part numbers you tend to lose more of.

Mika: Based on what we hear you saying, we're not so sure we have a problem with the board layout [1:1 between board and interposer pads, non-solder mask defines pads], but with the flawed execution of the layout. If your board fabricator decides to

Hi, There is lots of threads on this, so I would search these, and then do some reading. Then once you have some brands in mind, call the suppliers of this equipment and get some demos to learn about how each machine works. There is lots of differen

Well, what I have takes data directly from the Protel 99SE placement file, so in the present form it is a bit specific. This file is simple ASCII text, but the layout of columns will be different on other CAD systems. What I have has a number of sh

We have had issues with using the ones from Best. The holes are not always cut correctly and the edges (inside the holes) are not well defined because of the kapton material they use maybe. Plus you leave the mini stencil on the PCB under the BGA whi

Apparently because the machines are old and prone to break down they do all the printing for the day (maybe 6/7 different board types) up front. This doesn't make any sense to me - if the machine is going to break down, the machine is going to brea

Thanks for your reply! Have you tested the torque meter yourself? I have asked our supplyer if they had any but the answer I got was that they should check with Fuji, and that semes to be a slow process... We do mouthly mainteness on our highspeed fe

I can post that info when we get it from our design team. All we have right now is a drawing and a BOM calling out "mini fuse" of 5 different values. The clip/socket is not called out at all, but going by the shape on the asembly drawing & mask lay

There are several alloys had been using in the industry. For SMT: most people use SAC305 For Wave: most of them use SAC305,SC100C,SCS7,and SACX0307. Of course, different alloy composition have its own recommended profile. There is no such rule tellin
