hi, does anyone know what type is Carlo Gavazzi sensor on REHM SMS2 reflow oven? The only marking I see on one I have is "Tripleshield tm"

Hi! I have just checked in my same oven after a blower-defect. You need Carlo Gavazzi EC3016PPAPL-1 sensor. You can find a link here about the sensor, use it as reference: https://us.rs-online.com/product/carlo-gavazzi-inc-/ec3016ppapl-1/70014680/ It

Reflow soldering de-ages the capacitors. Two things may be affecting your testing. * Capacitance measurements are often erratic during testing for about 10 hours after de-aging. * Test limits should be set so that the capacitance value is within the

Hi Does anyone have any experience with assembling pcbs that have embedded capacitance ? are there any do's and dont's over and above manufacturing a standard mulit-layer pcb ? Tahks inadvance Milas

Thx for the replies. Acutally I am doing a process related study to see whether the process (pcb depanelling)can induce crack to an MLCC. After depanelling, I will do a thermal shock on the MLCC based on IEC 384-1, that is, five cycles of 30min at hi

Hi, Anyone ever have an issue with stray capacitance when using no clean solder paste. We are having a timing problem on one product. The problem goes away when we clean the assemblies. We use a no clean process normally. These assemblies worked

Hi Has anyone has thermal capacitance model for QFN (9x9) package with exposed pad 7 x 7 (or 6 x 6). Ideally between junction and case, junction case and board (JESD51-7 or similar). I wish to do transient with spice, to established how long it tak

We have been experiencing an issue where our Panasonic film caps on a board are losing their rated capacitance. We are well within their recommended reflow specs and no other operation exposes the part to a temp of more than 160°C. The caps will read
