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

If any changes in design is not possible and you have to solder it, it's a real headache, I know... I see only 3 options here that you can try consiquently: 1) Accurately profile the board and optimize a profile (go to lower limit of process windo

Hi, AJ, In general, the peak PCB temperature is variable depending on the profile used. We try to keep our peak temperatures in line with the paste manufacturers recommended temperatures; ignoring the peak temps for the PCBs. For the peak temps yo

Just wondering if anyone has a Heller reflow oven and is currently or in the past use Tribol 1421 high temp chain oil. Thanks.

I worked for Electrovert for 20 years and up till today the 1421 is still the oil of choice. The chain doesn't care who's oven it's running in but it does require regular lubrication.

Hey all, I have 3 questions about reflow. Hopefully someone can help me. 1. I am having a problem. I set the peak at 230 and my mole thermocouples are telling me the temp in that zone gets to 237. How is this possible even if the thermocouple

Campos, This is a direct reply I recieved from Indium, (thanks to Rich Brooks), in late 2004 regarding SMQ230. I have followed these guidelines with good results using ENIG finish. Same also applies to Indium 5.1 apply to both alloys (SAC 387 and 305

There are ledgitimate reasons for checking furnace calibrations, but let me clarify what that is. 1. TC's are not necessarily calibrted. Not unless you need "absolute" accuracy. TC's operate against a (non-linear) standard +/- a tolerance. Most
