I am building a high voltage capacitor discharge device and due to ownership issues, I cannot post the schematic.
The schematic calls for 4, 50W, 1k resistors along with a few diodes and 2W resistors.
The original I seem to remember was done on a PCB but I wanted to try something different.
I am going to glue the 50W resistors on one side of a proto board?, and wire wrap the other components on the other side. In am not sure what the board is called. It is about 2.5 x 3.5 inches, the holes are copper clad and they are not connected. I plan to poke headers thru the board as needed.
So, I am asking if the mix of glue with headers will interfere or have an unwanted effect on the electronics.

The 1st thing that comes to mind is heat. If the resistors get really hot I wonder what will happen.

What do you think ? And thanks.

 

Here's a snippet from the TDS for that Loctite cyanoacrylic glue (CA)):

CA glues can be reconverted to the monomer (what's in the bottle) by heat. Loctite makes other adhesives that are more heat stable. Some are electrically conductive and others are not. McMaster-Carr or any other distributor will have information to help you decide. 3M is another adhesive manufacturer. The offerings are enormous.

 

Hello,

When the resistors will get very hot the PCB might burn.
The dissipation of the resistors the will be MUCH lower as on a heatsink.
Without a heatsink they may only dissipate 6 to 8 Watts depending on the surrounding temperature.
(see the datasheet for more info).

If you are going to run 50 to 200 watts through the resistors, expect that board to start burning. How many watts are you actually dissipating?
Using heatsinks as mentioned before is a wise idea.

 

Put some stilts on the resistors. Need air flow.
