Overmoulding Silicone / Tpe Onto A Printed Circuit Board

Recommended Posts

Hey guys,

I'm a student trying to figure out how to manufacture a piece of wearable tech - wondering if anyone here might point me in the right direction.

The product is a wristband coated in TPE. What would be really nice is if I could overmould the TPE directly onto the PCB.
I have been in contact with a couple of companies, and their response has been a) to overmould a PCB, one must go for a low pressure, low heat solution. This plastic is usually quite rigid - not the sort of flexibility suitable for a wristband. B) silicone / TPE requires high pressure, high heat. This more or less blasts the components off the PCB.

Hence its tricky. However, I took apart a Nike Fuelband (http://i.imgur.com/yhZkoJi.jpg) - and it seems they have managed it. They have used some sort of TPE (I think but I can't tell), and they have overmoulded it directly onto the PCB - I was able to peel it right off the surface (perhaps some sort of coating was used?)

How did they do it?
