Alot of the companies out there use Standards developed internally, centered around there paste, equipment, and reflow processes. Normally you will see either 5mil or 6mil stencils used for everything in house with the exceptions of specific boards.(

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

Thanks for the input.... I ordered a 5 mil stencil AND used more tooling under the board. This gave me a much smaller deposit of solder. I wouldn't swear that was my problem but 96 boards later the problem is 99% gone. I believe there was just too mu

Depends on what you mean by shifting towards each other. Otherwise, 7 mil should be fine for 0603. I've used 6mil, 7mil and 8 mil without problems. Generally, stencil thickness won't have a bearing on "shifting" parts. Check placement. Make su

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 need some urgent informations on stencil design guidelines on how to perform epoxy printing on 0603 and 0402 components. Could anyone help? ( Reflow process is not possible because of some other constriants) Secondly, I need also facing a lo

I have been soldering 0603 components on the bottom side using a glue and wave solder process for a long time. Bridging has not been a common problem. However, it is inherent on the design engineers to follow good manufacturability planning when la

We have an LED 0603 package, We are using stencil of 5 Mil, Before Reflow placement is perfact but after reflow it tis found that there is more than 30% LED are tilt. Can the speed of Fan in Reflow can help or I have to reduce the PAD opening in Sten
