Discussion Overview

The discussion revolves around the challenge of adapting a PCB designed for 0.150" pitch header pins to accommodate a component with a 0.1" pin spacing. Participants explore various solutions, including adapters and alternative mounting techniques.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant seeks a simple adapter for connecting 0.1" pitch components to 0.150" spaced holes on a PCB.
  • Another participant notes that such a transformation is uncommon and suggests using wire wrap sockets for small quantities or creating a custom adapter for larger quantities.
  • A different approach is proposed involving cutting a rectangle of perforated veroboard to create a diagonal pitch converter, with specific dimensions and angles mentioned for the adapter.
  • The original poster expresses appreciation for the veroboard suggestion and provides additional details about the component's pin configuration.

Areas of Agreement / Disagreement

Participants present multiple approaches to the problem, with no consensus on a single best solution. Various methods are suggested, indicating differing opinions on the most effective way to adapt the pin spacing.

Contextual Notes

Participants do not clarify the feasibility or practicality of the proposed solutions, and there are no discussions on the potential limitations or challenges of each method.

I made a mistake on a PCB I designed, and have a set of through holes that are spaced 0.150" apart, when the component I want to put into it has a pin-pin spacing of 0.1". Does anyone know of a simple adapter that could go between these two sizes? I'm looking to avoid the time consuming task of running 16 individual wires.

I looked around on Digkey, and couldn't see anything for this.

That is not a common transform. How many rows and pins on the device.
For small quantities: Wire wrap sockets are still available. Splay the pins.
For large quantities: Make a small adapter for the IC to the PCB.
 
Alternatively; Cut a rectangle of perforated veroboard with 0.1” pitch strips.
The number of strips width will fit the 0.1” IC, the length of the rectangle being 1.118 times longer.
Cut the rectangle into two triangles and you have an 0.1” to 0.15” diagonal pitch converter.
The right angle triangle adapter will naturally have an angle of 42°, being the answer to the universe and everything.
You can mount the IC at that angle off the PCB or rotate it by that angle on the plane of the PCB.

Thanks for the sugestions. It is two rows of 8 pins. I like your veroboard trick.
