How do people prepare there solder paste for screen print? We currently remove them from the fridge and mix them in a 500g solder paste tub mixer to mix the flux and paste together we waste to much paste at the moment as we only use the tub for 1

Good morning, Solder paste softeners are designed to allow solder paste reach ambient temperature during shorter time period (only 5-10 minutes instead of hours). You are preparing your material in right way. No reason to worry. BR, Pavel

Thanx Dave/Hussman.. We normally store our solder paste in the refrigerator at 0-10 Deg C as per what the supplier recommanded. Our floor temperature is controlled at 22 +/- 5 Deg C and Humidity is at 55 +/- 5%. Recently we have customer asking fo

Good morning, I can recommend to use solder paste softeners, which can prepare solder paste for printing process. Softeners rise paste temperature by means of pseudo-planetary motion. Therefore, solder paste reaches room temperature during only 15

Hi Grant, The purpose for allowing the solder paste to reach room temp before production is to reduce the amount of water absobtion from the air. (e.g. a cold glass of water "sweats" on a humid day)The purpose for mixing is to make the viscosity more

Hi, It's removed from the fridge, and the tube is loaded into the stencil printer, however it's winter here right now, so it's still quite cold. It's Australia, so when I say cold, that's relative, however the room can be about 10 dec C in the morni

Good day, Search the net with "Solder paste softener", or check the links below: *Malcom http://www.malcomtech.com/products_sps.html *Japan UNIX http://www.japanunix.co.jp/ju_en/products/UM-103.html *Genitec http://www.genitec.com.tw/gam-60-e.htm

I ran this test back in '92 or '93 when Alpha was first pushing to change from Brookfield to Malcolm readings. The correlation between Malcolm readings to solder paste height is good. I could always look at the viscosity reading and know at least a d

Yes, the fine folks at Malcolm make this product. Search the fine SMTNet archives for this. Type the word: "planetary", and you'll find it! Trust me on this one.

Does anybody use a paste mixer in their shop? I am looking at one that uses "Psuedo-Planetary Motion" to mix and soften solder paste. If someone answers "yes", has this benefitted your paste consistency and improved your print repeatability?
