| To all who will be potentially my salvation, | | I am currently researching Polyimide stencils for possible use and manufacture. If I may be indulged - with due reference to all past enquiries and notes on the subject - can anyone offer an up to date opinion with regards to life expectancy ( number of passes ), ease of use & ease of cleaning. I recognize the Canadian source of a cut stencil is KJ Marketing but is there anyone else in the world making these? | | All help greatly appreciated. | | RICHARD | We've looked briefly at polyimide but my experience with it in flexible circuits made me look at other options. We too are a high mix, low volume manufacturer. We have over 2500 stencils relating to about half as many board numbers.
Currently we are trying to "break" Alpha's "Tetra" frameless system. It looks good so far and there's more flexibility with this type system. We retain our ability to use stainless etched, laser cut, step down types.
The huge advantage for us is to convert all our old Fuji frames to DEKs and to save enormous amounts of storage space. Also, per foil costs are about half that of conventional types.
