Is there any significant difference in the time required (average) to reflow a BGA component versus replacing the component? My company is attempting to determine the time to break-even for capital investment in a BGA workstation.

The assembly process involves activity before you get to reflow. Reflowing is the easy part. Putting paste down and placing parts in wet paste is the terrifying part. Benchtop reflow ovens can be a real handy tool for small production but with the g

My small R&D company (15 people) is considering the purchase of a bench top reflow oven & associated gear. The reasoning is that it would be nice to have reflow capability for 5 to 50 piece prototype runs in-house. As the only person with any real kn

Individual process steps are approximately the same length of time for reworking a BGA. You seem to be comparing the use of the automated SMT line versus an off line rework station. Consider that the off line station is a complete paste print, pick

How are you doing things now? I'm trying to picture a place going from no reflow oven to a reflow oven without also getting a screen printer at the same time. Are you now handsoldering parts on? With these batchs you plan on doing are you going to

As others have stated, there are a few other things in the aveage assembly shop that are much more scary that a reflow oven. For instance, we have a wonderful wave soldering machine and w've been doing that kind of stuff for tens of years, but every

Hi I think I agree with this poster. You will be surprised once you get the reflow oven working well how much you will say "And why did I do it the other way" I know, I know "I'm an artist" "I'm an inventor" Nothing wrong with being either yet

Currently we hand-assemble all prototypes, usually quantities less than ten. I mentioned the 5 to 50 number because a client will occasionally request more than ten, which has been handled previously by using an outside contract manufacturer (we are

Traditional methods of hand assembly are as you described. For a company that is concentrating on the 1-5 or 5-50 quantities you've described, you need to look for ways to accomplish your task with speed, repeatablilty, quality and at a fair price. T
