Having a selective solder machine without a preheat sounds ODD. Preheats are pretty important to drive off flux volatiles and activate the flux so it cleans the parts ready for the solder to wet to them. If you have no preheat then you must be expec

Your kinda vague on your description, How many components per hour, how many circuits per a day, week, month? what kinds and size of parts.? For a PNP setup for smt boards you will need a stencil printer(possibly manual or full auto like a DEK, 1 o

I would assume every EMS company runs into this issue on a daily basis. Before we get to how a machine handles it, I would recomend setting up an acceptance criteria with your board supplier... if you plan on accepting them at all. (ex. No more than

We run a Mydata high mix, low volume line. You can handle strips with either the Agilis feeders (losing the first 5-10 parts) or by placing the strip on the Y or tray wagons. For cheap parts like resistors, capacitors, some diodes and small ICs, ou

Seeing as you say you only have a small amount of cash ... I'd also consider a semi-auto printer where you align a golden board, set up the two cameras by boxing or overlaying a pad etc, and then use the vernier adjustment to get each pcb to align wi

Once a day is excellent QA but my experience has been that it's overkill. We check various products at the start of the run - it amounts to a couple of times per month at most. Over the years, I have not seen any problems with the ovens. The only

Talk to your buyers about forcasts. How do they know how to what to buy? They should be able to tell you what parts are going to be used on all the upcoming assemblies. Just make sure you don't get a purchase requirement report. That wouldn't inc

I would have said it sounded like a motor/encoder problem...but, since you found the broken resistor, that was likely the source of your issue. The resistor and capacitor are a filter for the motor, MyData likes to put them on nearly all of the moto

From the temps you list, I'm going to assume you are using leaded solder. What type of oven profile are you using: Ramp-Spike or Ramp-Soak-Spike? I think you will have better results if you use the Ramp-Soak-Spike type of oven profile. Better chan

Hi, I don't know what you mean by really odd parts. Are they SMT parts that have a flat surface to pick them up? If so, probably several machines can do it. I know for sure Siemens can place almost anything. THey will help you with any type of nozzl
