The whole process counldn't be easier. The sales reps' try to turn the whole thing into some crazy black art-its not. The stencil supplier will have their own standard 'glue dot' configurations, and 9 times out of 10 these are more than adequate. As

Hi, WE are making some test with this kind of component and aperture and here what we think. when you use a home plate aperture it's seem that the component is not lenght enought to have a good solder but maybe is our CAD guy that didn't make a

I agree with others here who have questioned the amount of solder and reliability of the joint when using this aperture shape. I have had experience with these with MELFS, and the main issue I've seen comes when cleaning the stencil - all those littl

We're unclear about what you're seeking, but in order to move the conversation along, are you looking for: IPC-SM-782A - Surface Mount Design & Land Pattern Standard ANSI Approved Get up-to-date land pattern recommendations for ball grid array pac

6 deg is std angle. Some machines have option to adjust angle from 5 to 7. Maybe yours does. If you have an Electrovert wave machine you can get the Omega option. This option vibrates the wave to reduce surface tension. It does a nice job on rectangu

Hi everbody, I'm facing some soldering problems with a Diode (SMA) during wave soldering process. During this process almost all the time one of the component pads have no solder, according to the picture dsc000604 attached. Some considerations: * T

Hi Dave, I think 6 sigma is here to stay. Unlike any other programs like ISO, six sigma goes to the people�s mind. With drastic examples like � you would not fly a plane which reaches its destination in a three sigma probability � you start to think

Hello, I'm a student assistant in a research project that deals with the simulation of PCB assembly systems. At the moment I collect information about SMDs. My problem is how to assign the correct feeder width to various devices in a simulation. Is
