We are currently handsoldering PCB jumpers. Does anybody have any experience on how the PCB-pad footprint design should be for screenprinting PCB jumpers to ensure that the connection is soldered?

Hello, I need to know the volume spread of solderpaste after screenprinting fine-pitch paste using a nickelformed screen. It is the end-result that counts , so of course the spread of metalcontent in the paste is important too. Can anyone tell me som

We use steel stencils. The adhesive manufacturer can give recommendations for squeegee type, material, pressure, etc. A lot of the tech data sheets include this information.

If spacing is not to small you could use a temporary peelable mask used in wave soldering. Or have your PCB manufacturer screenprint a peelable mask on for you. These suggestions are only if the mask needs to be removed, If not permanent solder mask

I visited the site. The guy with the green smock at the screen-printer looks familiar. I didn't find any info. on V-Score design.

Have you thought about switching to either automatic paste dispensers or rhemoetric pumpheads in order to contain the paste and only dispense what is needed during your shift ? I am not sure what type of printers you have, but I know both of these o

i'd like to have design information about how to produce membrane switches using the screenprinting process (making silver traces, buying /placing domes) Who knows where to find information? (we normally only produce the artwork)

transition automation made, what I feel, a good manual screenprinter and squeegies. Again is has everything to do with the component mix.

Hi: I would like to know their opinion about the critical variables that I need to control in a screenprinter(solder paste aplication on PCBs) process and how I can control them. Thanks.

I would try contacting DEK directly. As of last year, DEK fully supported these older generation machines. (Which is more than I can say for some OTHER screenprinter manufacturer. No, I won't name names)
