We have a granite table out on our production floor. We use the table along with metal parallel bars and a height gauge to measure component height. Some of these boards have components on them that may be ESD sensitive. Does anyone have experience w

Solder volumes is very important parameter to keep under control in order to get a good and reliable CCGA solder joint, and an automatic 3D paste volume inspection is strongly recommended practice to use. Questions: - what Column pitch do your CCGA h

What are the max temp specs for each of the components? this sounds like the real problem with lead free conversion. Which parts are which? Currently we are getting ready to reball lead free BGAs back to lead for a customer that had to be lead free

Hi, Yes, I think that's what he needs. Something that does fine pitch placement, but could also do faster chip shooting if required. Just a fine pitch placer might be too slow, but if he's only doing proto's then it might be ok, as time would be be

Need help from the experts on 1)simple way to measure the PCB warpage 2)what is the maximum warpage can the SMT machine allow the to accept and place the component without problem. 3)I have seen some people are using 7mils/inch as a Warpage spec. a

Warpage factors can cause: 1. Boards can not transfer down conveyor belts or wedge at transitions. 2. May not enter into machinery due to interferences (like board clamps) 3. May fall off conveyor chain in furnace. Especially true of thin (PCMCI

Hi there To all the MyData users out there who use Agilis feeders I would like to pose a question. What does your company do with the feeder sticks you have that get the tips of the plows broken off? Do you get them repaired or do you toss them aw

Grant, Yes they do get broken by the operator or whom ever is loading or unloading the feeder stick pulling the tape through the feeder and the component pocket will snag the tip of the plow and bend it so that the tip ends up breaking off making

Thats called technician syndrome (fine when your there and bad when you walk away). Is someone inspecting the board before reflow? If so make sure they don't touch it and run about 5 boards and see if it's consistent for placement. What type of pro

All, I am considering trying out the above to try and eliminate some of my defects on the wave process aswell as reducing cycle time etc. Incase of unfamiliarity with what it is : basically there is a Solder Preform present on the Header/Connector a
