Jeremy, well said! Thanks for "validating" my theory... LOL I agree that the sampling frequency, AND methodology are key things with 3D inspection. 3D will give you some insight onto how your paste (rheology, viscosity, thixotropy)AND process are

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

It makes sense. With temperature viscosity will change, and more liquidus material will flow better.

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

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

Hell as for storing the used paste have someone bring in baby jars. Yes I agree thats alot of wasted money if you throw it away every day. Plus since I'm on the subject why not use a bottle warmer? I persoanlly store our paste in a mini-fridge (along

Measuring solder static paste viscosity is fairly easy to do. IPC TM-650 .4.34, Solder Paste Viscosity lists the method and equipment. Just don't tell your customer that it is meaningless because the solder paste is printed in shear, not statically

Don't get yourself wrapped around the measure solder paste viscosity axel. Observe the paste handling and preparation instructions provided by your solder paste fabricator.

Hi Team, Please recommend some good solder paste viscosity meter.Which easy to use and user friendly. Regards, Ameen

Hi Dave, Thanks . But it's one of our customer requirement to have in house solder paste viscosity measurement. Regards, Ameen
