Q1. What is the recommended stencil thickness to apply the proper amount of solder for 0603 components? A1. The proper amount of solder is determined by: * Metal content of the solder paste. * Stencil thickness. * Aperture opening. * Other factors,

Hi, I am loading a new board with mostly 0603 packages. The pads are .5 mm apart and I am having a big problem with parts shifting towards eachother instead of centering on the pads. I believe this is caused by too much solder. I am using a 7mil sten

Eric, The Kolb RB6D (and the RB5D) are not ultrasonic cleaners. They are high pressure spray cleaners. I would not recommend high pressure spray cleaners for misprinted assemblies with previously placed components (unless you don�t mind solder pas

Good Morning, I have an application that we are tooling up for that has several LGA (Land Grid Array) components. The Gerber files from the customer has a solder paste definition of 1:1 to the pad. As I look at this part, I cannot believe that this

Aperture size should vary with the component [pitch]. That size should be the same a the pad size. So, generally pinching is not required. Indium discusses BGA apertures on their site [ http://www.indium.com ]

We agree with Russ. * Haven't used them in 10+ years. * Size of keepout for the stepped apertures needs to be large. * Manipulating aperure size to manage paste volume for specific components is not difficult.

Oh, I just remembered the other thing that I wanted to mention ... Do the pads match the component leads?

An experienced stencil designer suppose to check gerber data before making stencil it take 5 minutes to do this easily in computer after that analyze components if there's any critical parts in order to modify the aperture at USA STENCILS INC we have

I'm new to the smt game. I'm trying to learn the basics of stencil design. I've just been tasked with removing and replacing a couple of mictor connectors. I need to find/design stencils for the solder paste. These boards are proprietary, and we don'

Print material through stencil onto Plexi-glass and place Plexi onto your board. Sure, it may cause a little clean up but this where the metal meets the meat. Don't worry about ESD cause you have no component on the board yet (sorry Quality guys -
