if you can't change the PCB materials or design at this point, you might be able to reduce it somewhat through the use of fixtures or edge stiffeners. Unless it is a particularly thick board, I don't think the reflow profile would be the issue. The t

if use tray cannot solve the problem, you can change from the design 1）Reduce the effect of temperature on PCB 2) PCB USE HIGH TG 3) BOARD THICKNESS TOO THIN 4) MODIFY THE BOARD SIZE 5) Reduce the V-CUT depth.

I have never used a VP oven, but I did get a pretty good demo of one and was pushing hard for my company to acquire one. The issue ended up being that there was not an East Coast distributor for the "juice" and that became cost prohibitive to get sh

Hi Sir, The VP Machine that i am currently using takes reference from its own temperature sensor. so most of the time i would have to adjust multiple times for my PCB to soak at the right temperature or reflow for the duration that i need it to. Fo

Charlie B: You mentioned that you have an air conditioned environment and a RH 0rf 50, baking the boards is predominately done when the history of the PCB delivery and / or previous storage conditions are un known. When I was with a CM, we did this a

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We

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
