There are several different technologies in the industry today to assist in the out-gassing of flux cores. On automated soldering systems, there are two main types of perforating solder feeders: - Hole Drilling - "V" Scoring By perforating the so

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

Dear all, I want to know the difference between the CSP and the BGA (I think there is only in the mesh pin difference). Secondly, if their solder balls have same dia, LxBxH are also same with the the manufacturing of the pin coating chemical elemen

Comp is relay. I've pulled the spec. Max 240. Using Leister h/g with manual temp settings from 1-6 (20 - 600C)set by the operator. Gun was set to setting 4. They are using the heat gun to reflow the solder after SMT but before wave. High fai

Relays huh? I can tell you from previous experience that relays are not a good heat gun candidate. Did you check how long this part can withstand the 240? I do not know what the 4 setting is on a liester but it is probably well in excess of the 24

Guys, So I recently started working for a small CM in Southern N.H. We currently use 2 Magic Chef Mini wine friges to store the solder paste (63/37, RoHS). I've been monitoring the room temp (and humidity) and the frige temps all this week. The pro
