Discussion Overview

The discussion centers around the formulation of a non-sticky viscous gel, with a focus on its potential applications in electronics, specifically as a suspending or bedding buffer for PCB soldering processes. Participants explore various materials and methods for creating such a gel.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant suggests using base materials like starch or fine wood sawdust mixed with water and possibly glue, mentioning that acetone could be used to reduce stickiness.
  • Another participant inquires if the gel in question is similar to slime made with PVA and Borax, which can vary in consistency.
  • A participant emphasizes the need for the gel's viscosity to be reliable for use as a suspending/bedding buffer in PCB soldering applications.
  • A later reply requests more details about the specific application, including the type of component being soldered and the soldering method used (reflow or wave soldering).

Areas of Agreement / Disagreement

Participants express varying ideas about the materials and methods for creating the gel, and while there is a shared interest in its application for PCB soldering, the discussion remains unresolved regarding the best approach to achieve the desired properties.

Contextual Notes

Participants have not yet clarified specific assumptions about the properties required for the gel or the exact nature of the PCB application, leaving some aspects of the discussion open to interpretation.

TL;DR
How do we make our own non sticky viscous gel
How do we make our own non or very little sticky viscous gel as ever overheard and glimpsed a chat circle of 3-4 persons conferring one another about how making it correctly and had successfully realized one in hand of one of them

But that casual time quite short so one would have no chance to learn or perceive of it well, Iirc it involved base matter e.g. starch or maybe fine wood sawdust mixed with water and maybe glue, then if too sticky it'd be neutralized with some acetone (or s.t. else better)

Anyone really gone through it so that will share experiences now please ?

Is this the slime you can make with PVA and Borax? It can be mixed to be slimy or a firmer version called flubber.
 
Unfortunately haven't heard that due to my noobs

The point is the gel viscosity is needed to be used reliably enough as suspending/bedding buffer for PCB onto which a component is being soldered

Looks like you came to the right place; I'm quite familiar with various PCBA assembly and soldering processes. Can you say more about your application? What kind of component do you need to hold in place for the soldering process? Is this reflow or wave soldering? Top side or bottom side of the PCBA? The more details you can give us, the better our answers can be.
