Has anybody done any pin in paste job with a dispenser? I read somewhere that the needle i.d. should be slightly larger than the hole diameter, but with holes of 1.4 mm I would have to work with a very large needle indeed. How does paste work with such a large needle? Has anybody tried using smaller gauge needles? What kind of dot pattern have you tried? I tried dispensing four large dots on the hole edges with a 0.58 mm needle (obviously you can't just squirt some paste into the hole with a small i.d. needle because it just falls through) and got surprisingly good results but solder beading seemed to be a problem (also due to the component not being designed to pin in paste work, with no proper standoffs). Any ideas?
