DaveF is correct in saying that TAL is not the best metric to use in reflow soldering. That is why paste manufacturers give such a wide range; typically 30 to 120 seconds. The peak temperature is more important, especially in the mixed Pb and Pb-F

Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time

I built myself a reflow oven using an off the shelf 29l fan forced oven with digital controls. I then fully insulated the cavity around it with kiln fibreglass, and added a metal infill at the back as the back of the oven was just a metal sheet. Anyw

Hello all, My company specializes in pcb design and subsequent prototype assembly. With that core of business, we will assemble up to 10 boards a week. We currently hand solder and use a reflow hotplate for these boards. We have been getting reques

Can anyone tell me if there is a formula for finding the after reflow height of solder with no part attached? I have to print some pads that do not have any parts but there can not be more than 1.5mil of solder on the pad after reflow. I am going to

can some one give me some suggestion to solve the problem. we are using cooksun/alphametal rma9086 paste for our screenprinting. after the reflow we see lot of solder ball on the board. we have maintained the exact profile given by the manufacurer. w

10% slump). I am finding out their test std used but I think those lab test is different from real reflow as the heat transfer rate of reflow oven is much higher. Any one care to share your views?

Hello, I am new to the SMT area and I need to know what a "good" vapor phase reflow profile should look like. The fluids we are using have a BP of 45 C and 219 C. Thanks,

I am most familiar with Heller (10 yrs. of 1088 4 zone - 1800 8 zone ovens) and find them to be very reliable. Other Manufacturers may have five zone ovens on the used market. (I used Petlock as an example because you could get data sheets/specs from
