Greg, you pointed out yourself the many advantages of bulk feeding. I would like to mention that the higher component accuracy and the feeding track accuracy of the bulk feeder contribute to an improved pick failure rate of small ( 0402�s ) component

Hi DaveyF, Thanks You see, you proved my point, with piles of more information than I gave. Based on Application rather than design and manufacturing specifications, a lower IPC class can out perform another. So our starting Poster must look at t

This may be a really silly question but does anyone pick up and hand place the reject parts from the scrap bins of the machine? My attrition rates are out of control and i think this would not only highlight the problem but also save oodles of money

Sn/Cu/Ni is introducted to me in wavesoldering lead free process. Around in our industry, we have a plenty of info. about SAC but not on this alloy. The distributor showed me some information about this alloy including less dross, more shiny /smoot

Hi I had to poke around awhile to see what you meant. I think you were at an advanced level where IF he knew the MSL ratings of his devices he should constrain his profile within the component mfgs tests for exposure to various profiles, or at leas

The main problem I am having is getting the Rising slope 1-3 degrees. If I slow the conveyor down then I have too long of a reflow and if I speed it up then my ramp rate is too high. I was not sure if I need my first zones at a low temp or higher t

I would believe that the connector spec is for the max temp that it can withstand while the paste is the max temp that you need to achieve. Solder balls are usually from excessive ramp rates in the oven. I would contact the connector mfg. and see wh

if the capacitors are placed very near to the edge and their position is 90 deg than it may cause crack.4thly if the reflow ramp rate is more than 3 deg C then it may crack. 5th ly if the solderin tip temp. is very high and soldering bit is very thi

Dear Colleagues, I'm am experiencing some problems with nonwetting of primarily 0603 packages. The problem is infrequent but occures just enough for my QA dept. to notice. My reflow profile seems to be correct and the vast majority of parts solder f
