Hello, sir. We are a SMT equipment manufacturer from China. We have a hot-press soldering machine that can change your current situation of manual soldering on PCB board. In addition, we have a better reflow oven, the upper and lower two cold tempe

Hi, We have solder reflow use with water soluble flux and Tin/lead process. There is special glass component which needs to mask during reflow soldering and wash flux+solder mask post soldering. The existing solder mask does washes off. But leaves

You have a peak of 216 and roughly 40 seconds TAL. So you are right in the middle of the given ranges. So there's room to get things a little hotter and for a little longer. I am surprised you are having this trouble with TIN/ LEAD, as the process

"For the lead free soldering of electronic assemblies, the inclusion of silver in the alloy results in better wetting compared to non-silver containing alloys and also allows for a broader process window. Silver also improves joint reliab

How fast do you use your OSP boards? We don't use them but if we did I would want to try and use them the same day we open them. They are cheap but do not store well. Tin/Lead paste spreads much better than ROHS paste. If you can not always reflow

What do you mean by "But after performing temperature cycle test, the former aging rate (from the shear strength ) seems faster than the latter."? Comments are: I can't recall having heard the term "precipitation hardness" [not that that means anyt

We build a product that requires a lithium battery. There is a Smt Battery clip soldered onto two gold pads on a FR4 PCB. The battery is forced by two little clips punched out to provided downward pressure in the battery holder, enabling the lithium
