I sent you a couple of charts to assist with your troubleshooting. One is the Electrovert Wave Solder Troubleshooting chart and the other is Sandia Labs/Electrovert Optimum Solder Contact Time. Electrovert has a 6 deg. conveyor angle standard on the

I've seen this problem on more than one wave,What i've done is to run the conveyor a little faster,use a solder temp of 505 degrees F,and most important is to make sure that the solder is flowing over the back. this will keep the thin buildup of dros

I do not know about the cost issues but as I recall the tolerances are tighter on bulk components and this usually means higher cost. I cannot find my bulk feeding summit information but these links give you some idea what was discussed. I don't kn

Currently we hand-assemble all prototypes, usually quantities less than ten. I mentioned the 5 to 50 number because a client will occasionally request more than ten, which has been handled previously by using an outside contract manufacturer (we are

Hi All, I have observed this problem with one PCB supplier, the portion of the PCB area affected was cut and observed in SEM (Scanning Electron Microscope) and submitted to an EDX (Energy Disperse X ray analysis), finding Phosphorus levels higher

Hi Enrique, I don't remember all the energy levels that make the techniques you or your associates are using, effective. Each energy level yields information that must be understood is the best that I should give. HEY Based on my comment, does this

Because it's not limited to one part type and he's verified his profile...what else is there, unless the profile isn't what he thinks it is? My question is, why does it stick to the boards but not the parts? Is the difference in bonding strength i

In the early days of SMT we were using vibratory bulk feeders for chip components. It was quite obvious that some of the components had to try several times getting through the gravity trap or with the right side up through the light sensor. As a res
