Heatshrink plastic bag for small PCB
« on: June 28, 2018, 07:26:48 pm »
Hi all,

We're developing a small PCB with a DB9 connector in each end (~5 x 4 cm).
For this we're looking for a simple "wrapping" to protect it - and we thought of heatshrink plastic.

However, we're not familiar with this and wanted to hear if you have suggestions for where/what to look for?

Thanks,
Martin

Maybe 5/8" or 3/4" heat shrink tubes with at least 2:1 shrinkage?

Yes, though you probably want an adhesive lined heatshrink if you want to have a more robust shrink sleeve. Otherwise you can get by with only a cheap shrink sleeve, as used for bottles, instead of a regular heatshrink sleeve, or even use a shrinkable plastic sleeve like used for wrapping regular goods.  Otherwise look for heat shrinkable tamper proof seals as an alternative, I am using some as shrink sleeves and cable identifier protection, as the ones I got do fit over a BNC plug with ease, and are transparent as well.

A quick check on ebay showed heatshrink tubing in sizes up to at least 100 mm in clear or many colors.  Some had adhesive lining, some didn't.

There is also the choice of normal thickness and the thin version used to hold battery packs together.

Just search for "heat shrink tubing battery pack" on eBay and you will find several examples. The thickness is around 0.1mm.
