John, you mention yourself that this problem is component related. Is the 1206 presented out of a plastic tape?. The tape could be more slippery than the paper tape and the cover tape may pull the tape out of position. I am not familiar with the Juk

Bernard, The problem we have is when unloading the feeder several components may be lost due to the partial peel back of he cover tape. This area I am referencing just passed the point of the knife to the pick area. Also matching the correct feeder

We actually did try dots, 1/8" to be exact. We found that they were hard to peel off using just your fingers. Also, the manufacturer punched the dots too deep and ended up going through the backing on many of them. However, using tweezers, it didn

Hi We are trying to solder a a contact whose base material is stainless steel, this is then nickel striked with a gold plating of upto 3 microns. We are trying to hand solder this to a standard 1.6 FR4 PCB with a HASL finish. We are seeing problems

Square-leaded pin headers will typically bridge at the trailing edge (last couple of leads), since during peel-back, the solder at the trailing edge has "nowhere to go". If you have control over designs, ask your designers if they can put solder thi

Patrick...I'll give you a couple of examples. Wave Soldering, the Science: you're getting solder shorts and you slow your belt speed down just a bit knowing that this effectively lowers your contact length and improves your peel-back for that tou

we have never had a problem using no-clean flux as far as far as shorts and testing problems, using high pressure test probes helps overcome this. The problem we have had is if a unit comes back down the line a couple of years later we notice that t

I'm guessing you're running small batches of boards on the MyDatas. We had the same issue with management when they decided to save on parts (not realizing it cost them more in time and more frustration for us). We had Agilis feeders so that helped.

I like to find out more about your feeder manufacturer. Known problems: If the cover tape peel back is located in the pick up window, the tape may lift the component out of the pocket and when the component falls back it could be inverted. The co
