Solder paste stencil frame adapter
« on: October 29, 2021, 08:35:54 pm »
The solder paste printer I'm about to buy can only handle 29" x 29" frames.  Given how every frame I've used so far is less than a quarter of the size, the seller offered to find us a frame adapter.  Does anyone have experience with these?  Do they hold stencils securely enough, or should I find another printer?

Yes. We purchased this one for our Ekra X4 and very pleased with the results. Now we can purchase $30 framed smaller stencils from JLCPCB for our builds without having to buy and import 29x29 stencils at crazy prices. In hindsight, it was silly for us to buy the larger stencils.

You buy through Elissa (our rep) at their factory.

Could you tell me how much you paid and more details on how to use the machine?

Bought stuff from Elissa before. They supplied very good quality feeders at very competitive price and 2 years warranty compared to others that are mostly 1 year. Buying more stuff from them on this coming Monday!

I am also looking for an adapter for my VectorGuard frame.

Your link takes me to the home page. Can you please link again or indicate in which section you found it?  TIA

Our MPM UP2000 takes the 29" frames too. There's definitely no need getting giant stencils for doing smaller panels - you pay extra in both the stencil cost and the freight!

I created the attached adaptor from some aluminium profiles welded and bolted together. It can theoretically be modified to suit multiple frame sizes but to make life easy we've standardised on 550x450 stencils.

We paid $375 usd FOB Shenzhen. There are assorted shipping options from Shenzhen such as air courier or ocean. You can test door to door delivery with FedEx or contact a freight forwarder in Shenzhen. We can post some contacts if interested.

The stencil adapter is a very clever design and is adjustable to permit varying frame sizes. When ready, pneumatic clamps are used to lock down the frame so that the stencil does not move.

Can post some pics once at the office.

Well worth the purchase and we have saved $$ with the use of smaller stencils from JLCPCB. Many of our designs are quite small so now we can use small stencils that the Ekra X4 could not without this adapter.

The alibaba link seems to be broken.  Do you have another link, or pictures?  I'm very interested.

In the UK/EU adoptSMT lists loads of stencil frame adaptors, I presume they are fairly universal even if marked as MPM/DEK/Whatever and given they have so many I would also assume plenty of other places also have 2nd user versions of these hanging about

I think its too expensive for OEM use.  I can see it being worth it for a CM.  I think 29" framed stencils run $60 shipped to chicago from jlcpcb, smaller stencil may save $10.

May I know why you guys needs a 29 inch stencil at the first place? Is the solder paste dispenser machine can only accept this size?
I remember many years ago I brought my 400 mm x 300 mm framed stencil to a CM to discuss a job, they were laughing at the tiny stencil size.
But, they did acknowledged the quality of the stencil opening is very good (bought from China's King Full on Taobao back then).

Older automatic stencil machines are generally set to 29."  Newer models have a rail system that allows to adjust to stencil size.

100 per stencil shipped. If you have multiple stencils you pay multiple shipping from JLC - quickly adds up.

Even then the adjustment often has limits, speedprint stop @ 23", the documentation for ESE suggests rather than freely adjustable clamps it has presets and so on.

I have been wondering about semi automatic stencil printer with vision lately.  We dont change boards that often, and was thinking about making dedicated stations for certain pcbs.  I would prefer something without an OS.   Also small form factor.

I ended up buying the stencil adapter as suggested.  So far it seems nice, though my printer hasn't arrived yet.

Pros:
-Very nice machining
-Easy to adjust to different stencil widths.
-One pneumatic switch very securely clamps or unclamps the stencil.
-Two different sets of piston brackets were included.

Cons:
-The instructions are terrible.  The pictures are barely visible, and show a different model of stencil holder.  I managed to get it assembled, but it took longer than it should have.
-Pre-cut hose pieces would have been nice, or at least include the lengths in the instructions.
-Many of the metal pieces hadn't been cleaned after machining.

Sorry to revive this old thread. Can I ask what about this frame adaptor makes it printer model/manufacturer specific? I made an enquiry about this adapter and when I provided the potential printers I might be using it with, they replied they didn't have a compatible version.  Now I would prefer not to have to make my own if possible and I don't fully understand from the grotty pictures exactly what this item looks like fully assembled or what compatibility issue sit might have with a printer. Surely if the printer takes 29" stencils it fits and it works? Am I missing something or are Smtwenzhan just playing safe by excluding printer models they haven't met. (I asked about EP710 or an ESE ES-E2)

Just read this last post. I was in Shenzhen last October and met with this vendor and Elissa. They have a serious and active business model in China. I think that they are playing it safe with this stencil adapter.

If there is an interest - on Monday when we return to the office, can share pics of this adapter.

IMO, the designer deserves an award for the flexibility of this adapter. Our Ekra is pseudo-flexible on the framed stencils that can be supported. We play the wire on sourcing smaller stencil from JLCPCB as we save a great deal on shipping and on the actual stencil itself. This frame adapter is built like a tank and is (for us) a heavy unit to dance with while performing the initial setup. So far, has not let us down.
