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 Dougs, Check out the PBTs (Peak Body temperatures)and time at these temperatures. Remember that they sit higher in the ovens than most other parts. If you have problems getting that data I should have it for Tyco, JAE, Hirose, Harting & a coupl

A thermocouple is a set of two wires welded together at one end, where a junction is formed between the two wires. Because each wire is composed of a different type of metal, each wire reacts differently to the temperature of the junction. Because of

First and fore most is to find your paste manufacturer spec sheets. Read it over several times and let it all sink in. Then call them with questions as they want to keep your business so their engineers want to help you use their product. I assume y

Hi, when we change model from reflow temperature profile to temperature profile for glue, we always open oven to cool down. It is good for oven? Thank you for your answer.

183C, 60 +- 15 seconds). The quesiton to use a straight ramp or soak profile comes down to the product your are soldering. The key is to get the whole assembly at the same peak temp (minimized delta) and same TAL for effective formation of the so

We run double sided surface mount boards through our Heller oven without any parts falling off the bottom side unless they are too big/heavy. The trick we use is to set the bottom side temperature in the final 3 heat zones 10C-20C lower than the top

I measured the temperature rise when I built the unit and it has a nice linear rise in temperature over the 3 minutes. I have used the Quikees before. The galcon gas stinks and must be evacuated. The galcon is expensive. The galcon is a perflourocar

Dear Brian, I came across your question on the SMT Net and thought I better reply to this one. Perhaps you might remember me. My name is Brian Stumm and I work for ETS, Energy Technology Systems. I believe we met in Anaheim, CA during last years Nepc

Tg is just a way to say when the board goes limp... or a quick way to rank laminates... who cares. For lead free you want to look at Td, Decomposition Temperatures. ( Temp at which the material weight changes by 5% )
