Most glue suppliers recommend chemicals and methods for removing the product from stencils. What does yours suggest? Further, search the fine SMTnet Archives for background discussion.

Hi Jessie, Wrong market - we print solder (or glue) onto boards in 3D, then place components into it, then put it through a very hot oven, for it to liquify, then solidify, fixing the components to the board. Good luck with your venture, Rob.

Any Universal GDM users out there, what nozzle type are you using succesfully to dispense glue on 0603's? Single or Dual tip? How about standoffs? Thanks in advance for the info.

Bing, thanks for your reply. The nozzle that I will order needs to have standoffs, because we paste and then dispense glue (not my idea) So using the dimensions that you gave me I found the one that will work with our aplication. Thanks again for

two ways to attach a thermocouple first with hig temperature alloy (for example Sn Pb90) it's not very easy to inclose the thermocouple in the solder because the wetability of the thermocouple is awfull. the second one: attach the wire of the thermoc

You should be fine with this if it is a plastic body, If it's ceramic or some other kind of heavy package you will probably want to check. We process PBGAs up to 35x35 with no glue on many occasions.

Its been my experience that a "dot" of glue on the center of the part is needed for "barrel" type components.

We had this happen in a Heller 1808 oven when we placed Tant-A caps in glue (bottom side / no paste). We had our oven retrofitted to control the zone blower speeds. No more problem.

Are you using masking? Conformal coat will de-wet (no pin holes usually, though) due to masking tape adjacent to affected areas if the tape glue chemistry isn't compatible with the conformal coat.
