| During inspection and test we find leads which do not get soldered. Some are because of insufficient paste, but with others everything looks right. This will only happen on 1 to 2 pins, and it is not isolated to a specific type of ic or location o

we also have a need to measure the solder bond strength of our gull wing parts on our pwb. there are many published comparisons between eutectic SnPb and no Pb solders out there. the number that comes to mind is about 10N to 15N. I have not looked

We recently had a discussion with customer's QM - he claims that calculations for a proper solder wire diameter and soldering iron tip size (and temperature) have to be performed and documented for all manual (T/H) solderings (based on component size

Is anybody using H2O washable solder mask that comes on the PWBs you get from the fab vendor? I am researching PWB vendors that can provide this service. Thanks.

We have done Paste-In-Hole process for 4 years.I think this prcess is suitable for 28-pins connector. Of course, you must assure the connecotr can endure high temperature firstly.Secondly, you need calculate the volume of solder paste, you can refere

Is there a risk of popcorning plastic components during wave soldering? (The PCB is first surface mounted, reflowed and washed. It is sometimes left in air environment for as long as 48 h before the throgh hole components are mounted and they are wa

hi, This is moisture problem, I think.I have similar problem.You must try to bake PCBs.I bake our PCBs in solder wave mashine , under solder pot.There T is about 80*C - after 6-8h the PCB is dry regards

Why don't you use peelable/washable solder mask on the SMT components next to the T/H pins? Then, you won't have to worry about keeping the tight tolerances.
