Hand Printing using Nanocoated and other High End Stencil Materials

May 29, 2019 | Bob Wettermann

There are times when a PCB prototype needs to be built quickly to test out a design. In such cases where it is known early on that there will be multiple iterations or that a "one and done" assembly will be made that there will be some SMT assemblers who choose to hand print solder paste onto the board using a "frameless" stencil. In such cases where hand printing is used, the consistency of the printing technique has typically been in question. Furthermore, the effectiveness of both the nanocoatings as well as the higher end stainless steel materials, which have been heretofore studied in controlled printing environments, will be evaluated for their impact on the hand printing process.</p><p>The purpose of the study was to determine the effectiveness of select nanocoating materials as well as certain high end stainless steel stencil materials as they relate to the manual SMT printing process. A variety of nanocoatings were applied to SMT metal stencils and solder paste volume measurements were taken to compare the effectiveness....

Solder Paste for BGA Rework | Multiple Methods for Applying Paste Flux

Mar 30, 2017 | Bob Wettermann, BEST Inc. MIT

There are multiple methods, each with its associated benefits for given applications, for printing either solder paste or paste flux for BGA rework. Each of these methods is best-suited for a given situation, board layout and skill level of operators performing the BGA rework. This discussion will layout the various methods and present the specific circumstances for which the specific technique is most wellsuited. In addition, the pluses and minuses for each of the approaches will be discussed in detail....

Adhesive Backed Plastic Stencils vs Mini Metal Stencils

Aug 27, 2015 | Bob Wettermann, MIT

Ever since there has been a widespread usage of surface mount parts, the trend of continued shrinkage of devices with ever finer pitches has continued to challenge PCB assemblers for the rework of same. Todays' pitches are commonly 0.5 to 0.4mm with packages of tiny outline sizes, 5 -10mm square, making the rework of such devices a challenge. In addition to the handling and inspection challenges comes the board density. Spacing to neighboring components continues to be compressed so the rework techniques should not damage neighboring components....

Performance of Kapton Stencils vs Stainless Steel Stencils for Prototype Printing Volumes Processes

Jul 03, 2013 | Bob Wettermann, Hung Hoang

It has been demonstrated in numerous pieces of work that stencil printing, one of the most complex PCB assembly processes, is one of the largest contributors to defects (Revelino et el). This complexity extends to prototype builds where a small number of boards need to be assembled quickly and reliably. Stencil printing is becoming increasingly challenging as packages shrink in size, increase in lead count and require closer lead spacing (finer pitch). Prototype SMT assembly can be further divided between industrial and commercial work and the DIYer, hobbyist or researcher groups. This second group is highly price sensitive when it comes to the materials used for the board assembly as their funds are sourced from personal or research monies as opposed to company funds. This has led to development of a lower cost SMT printing stencil made from plastic film as opposed to the more traditional stainless steel stencil used by industrial and commercial users.This study compares the performance of these two traditional materials and their respective impact on solder paste printing including efficiency and print quality....
