There are a number of manufacturers of Benchtop Hot air stations. For what you are describing, look at Hakko as well as A.P.E. (if they are still around, they made a great little machine called a ?Chipmaster?, and if you added preheat, I think you

We currently have a single SMT line consisting of a Sanyo chipshooter in line with a Siplace 80F4 and we are soon going to install a odd form placement machine (probably JOT) into this line prior to the oven. This means going to intrusive reflow, whi

| Hello, | We are currently trying to design and ultimately implement a system that will be able to count and manage component placement for three Sanyo chipshooters on three SMT lines. | As the number of components decreases in the reels we want to

Ken: There is no complete package solution to the concerns you have. You need to weave you way through this project. I�m generalizing when: Placement machine OEM: * Knows their machine (your interests are served if this is the proper machine for

Hi Kurt, I agree with Dave F. I had exact same problem with PBGA placement. We requested our PCB vendor to plug/tent via (button printing) after HASL with SR1000 which worked well in the long run. There are couple of failure modes associated wit

Charles, The percentage of misplaced components can increase with the number of components, because as you increase the number of placements the travel of the PCB,for a fixed turret machine, increases in table speed and distance. The slower the trav

1. Verify all the part had load to machine. Get ready for the profile. 2. Run the board with double side tape. Is better to run one board for each machine. 3. Verify all the placement ( missing, misalgnment,etc )and check the value using meter for a

Certainly automatic placement, preferably with vision system assistance will yield a more repeatable process. Process repeatability (paste deposition, connector placement, reflow cycle, etc.) will be your key to success here. Another possibility yo

The metioned process will work, but I do have 1 Question, How are the PTH comp. being inserted? If automated insertion is going to be used the process may have to change. Topside SMD - then Auto insert PTH, the reason for this, is depending on the p
