i think Dave night have meant what do the solder joints look like? (maybe not) Anyway, I personally wouldn't reflow these boards unless you have solder joint failures We (I) used to hardly ever exceed 210 Deg. during profiling until the leadfree stuf

I test pdb-boards on the mat it ain't work! Wrong > mount of bolts being outputted. is have something > to do witfh the rohas soulder on them? I will take a stab at translating. I test PCBs on a static mat but the test does not work. The output

Oh, well if you can profile, model your profile to the profile supplied by the paste manufacturer. Anything outside of their recommended profile is all experimantal.

Have you taken a look at our SolderStar range of profilers. We offer 4,6 and 12 channel versions. Our 12 channel system can also be connected to our Wave Shuttle product for wave solder machine analysis. Our datalogger are the smallest reflow profile

We've just completed an experiment for one of our customers using lead-free HASL. From a manufacturing standpoint, everything seemed to have run fine. Solder profiling seemed to be unaffected, pick and place was unaffected, and the end result looke

Hi All, I would like to get some advice from users who place rfshields pre-reflow and reflow onto board. We ran a batch a few months back and boards which had the shields reflowed failed to function properly ~ I was happy enough that the profile

Hi all. We recently expanded our assembly space and moved our Heller 1500 oven to a new spot. In the old arrangement, we used a Purex filtration unit, keeping the hot air in our space. Recirculating the fumes caused a massive headache in cooling the

Hi, We have a 5 zone oven and we use a RTS Profile. Our last zone is the zone that the reflow takes place. some basic analysis is as follows: TAL 70 secs, peak temp 210,ramp rate seems fine. A typical setting is : Z1 140 Z2 160 Z3 160 Z4 185 Z5 220

In one board we are using 213 SMT components out of which 23 components are lead-free and the rest are leaded. The paste used is also leaded. Do we have to make any changes in the profile of our reflow oven ? Also will there be any negative effect on
