Stencil thickness is related to PCB design and is not related to paste type. If you release with a 8 mil stencil then use an 8 mil stencil. Of course there are pastes that release bteer than other and what not but use area and aspect ratios to dete

Stencil thickness = 175 microns? If my math is correct, 175u=0.175mil, and if that is english units then it is inches. I'm not understanding this correctly, please clarify for my sake please, are you saying the stencil thickness is 0.000175 inches th

Use the volume of paste of your circular aperture as the starting point. Calculate: Volume = pi X (aperture diameter^2 / 4) X stencil thickness Determine the sides of your square aperture using the volume of paste that you calculated and the stencil

Hi, How can the life of the stencil be decided? As the stencil is used contineously the thickness go on decreasing. How are you all deciding the life of stencil? As visually its dificult to deide the solder paste deposited thickness, is there any t

You did not provide the stencil thickness or your aspect ratio. If your aspect ratio (Aperture width/stencil thickness) is less than 1.5, the paste will not release correctly from the aperture, leaving paste in the aperture. For example, if your pa

Does anyone have any recomendations on 01005 stencil aperatures? Stencil thickness?

I was hoping some-one would help you with this because I too would like more information about selecting stencil thickness. I have read some about apperature ratios, but this alone doesn't appear to be the only factor when chosing stencil thickness,

What is stencil thickness & what is the pitch of your component.What is your cleaning processor for stencil.

| WHAT SHOULD THE RATIO BE OF STENCIL APERATURE TO PAD TO GET GOOD QUALITY RESULTS. BY THAT I MEAN, A MINIMM OF SOLDER BALLS, AND LITTLE TO NO BRIDGING, SHORTS, ETC.. | RIGHT NOW WE ARE USING A 1:1 RATIO, BUT ARE INVESTIGATING REDUCING THE APERATU
