1) Adhesive dispensing -number of dot per component , what's the determined factor ? What's the distribution ? 2) What is the critical factor to monitor the consistacy of volume & profile per dot ? 3) What is the effect of temperature/balance of adhe

We machine place the first part, then add two dots of dispensable solder paste to the top of the terminations, then hand place the second part on top of the first. Reflow. It works better than hand soldering after reflow. The solder paste is dispens

Is anyone using Fuji GL's anymore for adhesive dispense? Do you also have fluctuating dot size issues?

Hege, can you share more info on the formulation you ended up using for the micro dot dispensing? I'm trying to find the proper metal load and viscosity for the auger valve dispenser that we are developing and it looks like the regular low viscosity

Thanks Rob. I'm not so sure in a mass production environment that using the mount spray and kapton tapes are going to be efficient. For solder paste dispensing, any idea what is the smallest solder dot size the machine can dispense?

Peelable solder mask works well. Hand dispense and peel off after. Paint sticks work OK, but it depends on the mfger of the paint stick. In both methods you hand apply after screen print. Your Dek can be taught pads to get by. You may have to te

With regard to measuring dot diameter on my dispensers, is there an easier way to calculate the Cp and Cpk values? This manual data crunching is for the birds!

We are trying to do a dispenser comparison study between the Asymtek Axiom X1020 with DJ9000 valve and the Camalot XyflexPro system. The system will have a dual purpose for dispensing epoxy dots and underfill. I would like to have comments positive

Has anybody successfully used an automated dispensing system to put solder paste dots on .5 mm pitch pads?? I need to replace some Meritec tsop sockets and I don't want to use the single site stencils for .5 mm parts.
