I have also seen on Heller ovens (even new ones EXL series) cross profile temperature differences over their spec of +/- 3 deg C, sometimes up to 7-10 deg C, 200-230mm from fixed rail. This can cause funny issues , profiling can cover this up and not

Are we now talking about some "Vintage Collection" cars or the regular ones that do not have much re-sale value? In the former case, it would surely be worth spending on maintenance. However in case of SMT line equipments, one should consider 7-10 y

Splitting hairs, I expect SIR of all solderability protection, including OSP, to decrease after reflow. What�s more, I expect the SIR of all solderability protection to pretty much decrease over time. The �comb pattern� test specimens meet requirem

I need to cure conformal coat on a 19" x 15" board. The material needs 7 - 10 minutes at 100deg C, but I have limited floorspace so I'm looking for an oven with about 36 inches heated length and 18 or more inch wide belt. The material we are consider

I've seen many comments in many threads about the positive attributes of SN100C (apparently mostly by salesmen). However, I have a concern for the higher temps that will be encountered when using SN100C (or Sn/Cu) vs. SAC305 (vs. 63/37), specifica
