Hi Tom If the DYNAPACE has SMEMA out all you need to do is place a two wire jumper into pins 3&4 or 1&2 depending upon DYNAPACE's SMEMA configuration. This will by-pass a Release signal and feed PCBs into the oven.

Hi, I've been using Fabmaster in my daily job scope for 10+ years. Currently I'm using version 11.0.0.70, there's two issues noted in this version and would like to check if any workaround on this. 1. Fabmaster would crash (terminate) intermittent

Here is how smema works: Machine A has a board to give to machine B. Machine A has an opto or a relay that will turn on or close when it is ready to pass this board to machine B. This is the "board available from previous" signal, telling machine B

Hi All, We are producing a veriety of RF related PCBAs in which we see Unsolder/Mislaigned on a regular basis. In these baords usually one of the pad is connected to a signal trace and the other pad is connected to very huge ground plane. This gro

We find it curious that: * Heat slug pad for Q19 didn't take solder, indicating a pad [board] solderability issue. * Signal termination pads for Q19 didn't flow well, indicating a poor thermal recipe or a pad [board] solderability issue. * Signal ter

It does look like it was setup for fuji or siemens connection. I did get the smema signals working; had to add the connections for pins 3 & 4 on both ports and move some of the existing connections according to the smema diagram. Also, I wasn't seein

Thanks for the reply. When you hit start on the printer, you can see it send the "start cycle (SMEMA)" signal, and it immediately goes to "awaiting board from upstream." This tells me that the printer knows a signal has definitely been sent and rece

Hello guys, I'm a new learner in PCB field. And recently, I have summarized some basic information I learnt on how to arrange the line on crystal oscillator, but I'm not sure if it is right. So I'll write it down below, hope anyone who may read my po

This question is regarding stencil design: I am having voids under QFN TI P/N LMZ20502SILT. I have attached component pic. Signal pin is 18X16 mils. Center pads are 31 mil sq. Initially I had stencil done with one mil per side reduction on signal pad

As far as the large thermal gradient I have on my thick and thermal heavy board, I've done quite a bit to minimize the gradient but not successful. it's like one pad is connected to a signal while the other pad is connected to ground, you can't bring
