Allowable bow & twist: Together, both IPC-A-600G and IPC-6012B represent the core IPC documents for describing the acceptable and nonconforming conditions that are either externally or internally visible on finished printed boards. IPC-A-600G relies

I've never seen successful printing with a step as deep as you seem to be saying. The keep out would have to be jigundous!!!! SMTnet Technical Library: https://smtnet.com/library/files/upload/Step-Stencils-laserjob.pdf I'd guess * Maximum step

From my experience, stencil thickness should be determined by your minimum component lead pitch and squeegee pressure will be determine by the type of squeegees you are using. Best method of checking whether or not your screen printer is set up and

If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

SMT-ers I notice that most suppliers provide data that is eye-catching but avoid providing data of significant technical relevance, such as Cp and Cpk. It would perhaps be a wise idea for standards to be formulated in this area. For eg., ma

John, As a supplier of squeegee blades, we ship them out in clear plastics tubes at the approximate length of the blade itself. The ends of the tube have simple slide-on end caps. After visiting many customers sites, I've found that most of them k

We are having an internal debate here related to minimum Conductor Width. Can you have your QA manager review this and advise. IPC-6012C-2010 3.5.1 Conductor Width and Thickness When not specified on the master drawing the minimum conductor width s

Krikies my friend. A good wave ogre will be able to look at a wave and tweak in a way to minimize contact length (by slowing the conveyor speed), thus improving peelback, and lower it to the bare minimum without disrupting it's backward and forward

I'm not real clear on what you're looking to understand, but let me get things started ... IPC-A-610F - Acceptability of Electronic Assemblies, 7.3.3 Supported Holes – Wire/Lead Protrusion Minimum length: You need to be able to discern the compone
