    direct heat stencil,where do you get it? and how to prevent warping?

    So, lately i found that for smaller chips like pch it is very difficult to reball with nondirect heat stencil. So i decided to try direct heat stencils...and while i am waithing some stencils to arrive i have a few questions:

    1. From who do you buy a quality direct heat stencils? i am reading that they can vary in quality and make a big difference...Any trusted sellers?

    2. I am reading also the problem of warping (curving) direct heat stencils...Is it because of quality of the stencils? or/and because some preheating is also required? and help and advice here?

      Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages

      The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

      Marantz SR5007 popping on volume change and mute in Direct Mode
      by BigOof
      Hi,

      I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes....

      detecting heat with IR LED receiver

      I have some dark IR led, and want to know if it is be situable to detect pure heat (not visable glow ir radiation) in well lighted desk?

      So, if I put hand over it in near distance like few centimeters, that detect rising heat, not covering it from light.
      Something like termal camera, but in one spot, any simple circuit?...

      SR40 90x90 stencil direct heat, where to find?
      by myth77
      Mostly i use 90x90 stencils for chip reball, then i remove stencil and apply heat with heatgun...and preheater...and everything is fine. But this SR40 pch chips are very small with lots of balls half milimetar from each other...and i am not happy with results... I get bridges and so on....So i was thinking maybe to reball these SR40 chips with direct heat stencils...but i can not find it in 90x90 size. I tried aliexpress and ebay...but nothing.
      Maybe someone knows place to buy? Thx

      Moto G84 short after heat
      by ludovik
      Hello everyone,
      i was reballing the power manger of a moto g84, after applying heat i tried to power on and it wouldn’t.
      i injected 1.5v to some capacitor that seem in short because both side beep if tested.
      when i inject i feel the cpu burning;
      since the cpu is exactly on the other side of the board, is that possible that the heat from the reballing damaged the cpu? do you know where i can find schematics or what can i do?
      i know this is not enough to explain the situation so if you need any other info ask me please!
      Thank you very much in advance
