BTU as well as most oven manufactuers have great products. If they fit what your looking for and can give you good support(preferably local) then you should not really see any quality problems with their products. With the oven max temperature of 300

The 237*C is under the inductor with aTAL of 48s. I worked on the profiles this morning an got the max temp up a few degrees and the TAL to 62s. I will check the body temp of the Elec caps. The rest of the board has a max temp of 247. Thanks Gm

I've only used vacuum reflow on LED boards but I have heard that Vacuum may need to be reduced depending on components. I can't find the source at the moment but it was a study done by Heller I believe. I would experiment with different levels of v

237C max is on the low end for SAC305, especially if you have heavy leaded components. I always went with 245C and above depending on the board design. I noticed the electrolytic caps. You need to check max temp with the manufacture on those. When I

The best is, create 2 different profiles for each PCB type. Then segregate or separate them and do not let them run together in one line. Switch to the proper profile settings each time you change to other PCB type. This is the best. Each PCB materia

Snehal, Look at the spec sheet for the paper phenoline PCB. Look at the max temp. If it is at or lower than 183 degrees C, here lies the problem. If it will withstand higher temps at a shorter durration, you can possibly speed up the belt but like D

Hi Davef & C Lampron. Thanks for your reply. since i'm using RMA9086 62/36/2 Cookson no clean flux paste.so what do you think if i will switch on to the paste without no clean flux for PP board is there be any chance that i get a +ve result. Awaiting

Hi to all, I'm facing a soldering problem with one of my series of Product, since we were using a two different kind of PCB 1.GE(Glass Epoxy)2.PP(paper phenoline) in later PCB if i will use the same profile of the GE then it will get backed more & i

Lead Free in 5 zones is tough sledding. Start with your manufacturers solder reflow profile and calculate your belt speed by looking at the recommended heating time for the solder paste vs. the length of your heated zones. Set your belt speed so tha

for backward compatibility applications (such as this), the higher melting temperature alloy (LF alloy) gets the priority in selecting the reflow profile. you are using too low temps for reflow. your LF alloy wont reflow at these temp and you will e
