We have an application where an assembly has to be residue (flux) free except for 2 SMT non washable parts. Currently those parts are post wash hand adds but the product volume is exploding. We want to run those parts in SMT, mask them using an aut

Hello Again. I little more information about the issue: when trying to zero machine head the spindles move up and down about 6 times before giving the error code. also I notice that all the LEDs on the circuit board are off. L11 - L18. and the nume

I tried to check for the emitter and the receiver and I notice that the receiver is screwed into the side of the head and not easily accessible so I decide not to mess with it. this is what I did. I activated all of the clutches for the spindles an

Hello, we have several generation of Siemens machines and one of our lines is ASM SX1 series. Machine is very accurate and reliable as a hardware, but in my opinion the software is their biggest advantage. Software is very powerful and can do things

Both Manufacturers and Machine Types are a good choice... Why just these two Manufacturers? Depending on your needs (Changeover times, Board Size, Part Size, Part Counts, Odd Form requirements, CPH requirements, and the list goes on), there might be

If you are 100% sure that the solder has reflowed (time and temp based), then just use an wood stick to wedge the part upwards. It just takes a little bit of "lift". I used a wooden Q-Tip end that I trimmed to a wedge using an exacto blade. Wait f

Hi, sorry for reopening a old thread, but i wanted to ask if there is a way to know at what temperature the solder melts if you have a chip with underfill? I thnk its lower then normal air-fill temperature since the underfill conducts heat better the

The melting point of the solder itself does not change when you have underfill. If the underfill conducts heat better than air, it will take less heat (and/or less time) from your rework station to get the solder up to the melting point. That makes
