Even though you use a no clean process, it is still possible that some type of fluid has created the "short". Production lines are notorious for using cleaning chemicals on PCBs to clean excess flux after rework on other areas. Unless this type of c

Hi, I'm a non-technical person working for a small MFG company that uses SMT. We are experiencing a high level of board failures due to "insufficent soder". Where is the best place for me to get data to bring myself up to a level of knowlegde on

We have an HSP 4796, if the feeder mechanism is the same, this may help you a bit. First make sure that the componet definition is right on the component library. Tape or Embossed. Second, the component thickness vs actual thickness. Is the pick u

We need more information to give you a good answer. Is this a leaded part (axial or radial) or smt? How big is the part, how much weight per lead? What is the end use environment, will it see any vibration? or temperature extremes? Some general com

Our solder irons are tuned to 700*F, but the in-use temperature varies according to the solder alloy and the characteristics of the board and components. Check some of the papers on multilayer ceramic capacitors. They get fairly specific, for insta

I assume you need vibratory parts feeder to improve your productivity for pin header assembly. We use lots of vibratory feeders for small, miniature mechanical parts. We also have a machine building department in our company that can handle your requ

Hi all, I am just wondering is there any other Lead Free Standard Profile for IR reflow besides the standard provided by Jedec ? What if the profile that i use is different from the one provided by jedec ? Lets say the peak temperature for Jedec is

Why all the fuss about BGA inspection?? If your reflow process is sound and your rework system is competent (i.e a PDR) they will be fine. Best advice I can offer is to srike a deal with an outside company who will inspect a small batch of your pro

Hi Jipp, If we are talking about 200-500 boards per month the main question is"Is it reasonable to go for semi-automatic production?". You will nead at least 1.Manual stencil printer 2.P&P machine 3.Infrared dryer or reflow oven Most expensive par
