I have a (new to me) Quad QSA-30A that I just got about a week ago. At first, I could get it to go ready most of the time, now it will never go ready. I have traced the ready button into the DPRAM board and the logic is OK all the way into one of t

Aurash, we own Yamaha machinery but just throwing it out there...are the movements of the motors smooth or with friction? Is it possible that the linear screw rods (as in our machinery) require to be lubricated? There are special lubricants for each

yes Once I was using dewers of liquid N2 and recommended switching. I tried using air to the machine so the sensor would let the machine run. Boards went from good to a two inch icicle covering a large area. We went to a wall mounted single stage fi

One thing about liquid N2 is while it is safe, only let trained personnel near it. I believe if someone got their hand frozen on the side, it is not coming off until the dewer is completely empty and warmed up. And make sure management understands

I think this probably depends a bit on what is in an ssa file (no idea personally)and how the machine you are moving to works. For instance if you have intelligent feeders than any data relating to where a feeder is loaded or the best place to put it

thanks Stephen!! I'm testing for voltage and have found 24v going through the E-stop to the main switch. If i trip the E-stop i can disengage the main switch. I have no more control to the hardware then that. The software is not throwing any code ot

I don't know this exact machine, but it likely has similar logic to some other Samsung machines. The E-stop buttons have TWO sections. One shuts off the "main start" button, the other informs the computer that the button has been pressed. If you d

Hello Jon, I appreciate your reply, correct there are 2 red (24v) that control the main power and 2 blue (they control the power to the units operation keys ready, start, stop, reset, change feeders.) additionally there is a red jumper wire on the E

Hi all, (I posted on eevblog also, figured I'd try hear as well since this seems like a semi "niche" question) I need some advice on PCB cleaning. Up to this point, our assembly line has strictly run NC paste, with all SMT parts. We never washed an

We have recently received some pre-tinned "flat lead packages" and the question I have relates to the definition of solder touching the component body of the part. Typically when I have gold lead parts tinned there is a gold gap between the tinned po
