Stencil printers, what to buy?

(1/9) > >>

Simon:
I am wishing to buy a stencil printer. The type that you put a foil stencil into and it gets tensioned in the printer. But what do i buy. For a zero income business/hobbyist these are not cheap but I have struggled with 0.8mm pitch chips and will be working with 0.5m and VQFN in the future no doubt.

So my candidates seem to be: the tecprint500 from CIF: https://cif.fr/en/manual-operated-stencil-printer-for-smd/285-manual-operated-stencil-printer-for-smd-tecprint-500.html

My dilema with this is that they do not explain what all the other parts are like the starter kit and the video is pretty poor showing an untesioned stencil that bounces up and down but I think that is user incompotence ans they clearly miss several areas as well, or is it that bad?

Or here: https://portal.multi-circuit-boards.eu/Shop these two models seem to do similar, one cheaper than the tecprint one more expensive.

Does anyone have any experience with these machines? or any other advice on what I can buy.

Make sure you have a good squeegee too!

You may not have considered the other path of buying a framed stencil printer and buying framed stencils.

Of course that increases your individual stencil cost, but longevity of that stencil should be higher.

Simon:
No i don't want to use framed stencils. They are £20-30 more expensive and it limits where i can buy them so i am further locked in. Even with a £25 saving in stencil cost to the extra £1000 it could cost for a frame-less printer After 40 stencils I have made my money back and as they are prototypes i don't need stencil longevity.

Simon,
I'm in the same boat as you...
I looked at the CIF printer, the video on the product page looked very "hmmm" to me. You can clearly see that the stencil is not mated closely to the PCB, there is a clear gap between the stencil and the PCB in the video. Now, this could be as simple as an operator error, but I would have expected a "product video" to be perfect....

I looked at the Spíde printers here: http://www.spide-smt.nl/products.html
The 3 different sizes runs at around €1100, 1500 and 2100 (ex vat) (note only the largest one has vertical stencil lift)

EDIT: It seems that the  "PAGGEN TSD240" is the Spíde-SD240 from the looks of it....

Regards,
Carsten

JLCPCB charges less than $10 for a framed stencil. Based on my experience, the frame gives you an extra rigidity and sturdiness resulting in better print. Even for 1 off prototype, I would use framed ones.
