| Does anyone out there involved in RF manufacture have any experience with the KIC Slim-Kic profiler? Do you find any interference problems between the RF transmissions and the testing of your products. We build primarily high-freq stuff like point-

I am trying to get a profile on a thru-hole board with metalic coating on both sides. My preheaters are about maxed out and my profile is just reaching 200 degeres F. I'm not sure how much I can slow my conveyor down to get more heat. Does any one h

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

I just ran into a reflow profiling problem with a new assembly that we are processing in SMT. There is a cluster of six or so electrolytic caps that measure approx. .710" wide by .660" tall. They are spaced .100" or so apart. When I run a profile, t

Good Morning Everyone, We have a customer that produces RF based assemblies. We are building several board types for them, all of which have an "RF" area of the PCB. This RF area does not have any mask to define pads. There are also several issues w

Basically the same exact way as a much smaller board. The only difference is the profile. Most of our boards are 0.063" thick. Looks like you found your problem. If the edges of the board are cold relative to the rework site (high difference in t

Would i be able to judge how good is a reflow profile from the appearance of the flux residue? Often times i come across flux (not sure if residual) between a non-wet QFP lead and the reflowed solder paste on the pad (it's sandwiched between the bott

Any decent flux would volatise off with the heat of the wave unless absorbed into the solder mask. Test this by trying to clean in alcohol or common solvent aerosol, if it does not clean then it is probably Mineral Salts from solder mask fillers. Ano

We are starting to see issues with using Kester WS R562 with lead free components. The joints look grainy on almost all of the 0402'2 and other small components. Some of the solder does not solder to the terminations. These are hybrid boards which

I'm testing SN100C, and with our 5 zone oven I seem to be able to fix one issue by changing the profile, but that might introduce a new problem. Some profiles work very well on most components, but have issues on other components. These are usually 0
