Challenges for Step Stencils with Design Guidelines for Solder Paste Printing

The stencil printing process is one of the most critical processes in the electronic production. Due to the requirement: "faster and smaller" it is necessary to place components with different paste volume close together without regard to solder paste printing. In our days it is no longer possible to control the solder paste volume only ....

SMT Manufacturability and Reliability in PCB Cavities

The aim of these investigations is to identify any possible criteria of a solderable multi-depth cavity PCB, which may affect manufacturability and/or reliability, and if so to which magnitude. Thus, we expect to locate general and possibly specific advantages and/or limitations of such a product under a standard manufacturing environment.

Printing of Solder Paste - A Quality Assurance Methodology

Solder paste printing is known to be one of the most difficult processes to quality assure in electronic manufacturing. The challenge increases as the technology development moves toward a mix between large modules and small chip components on large and densely populated printed circuit boards. Having a process for quality assurance of the solder paste print ...

Step Stencil design when 01005 and 0.3mm pitch uBGA's coexist with RF Shields

Some of the new handheld communication devices offer real challenges to the paste printing process. Normally, there are very small devices like 01005 chip components as well as 0.3 mm pitch uBGA along with other devices that require higher deposits of solder paste. Surface mount connectors or RF shields with coplanarity issues fall into this category. ...

Solder Paste Deposition Project Report

INTRODUCTION: • The mixed technology on a PCB is creating unique challenges for board assemblers. Solder paste volume requirement for castle like component and miniature components vary widely. Approaches to solve these problems are: • Dual print • Printing/dispensing • Overprinting • Hybrid approach • Step stencil

A Study of the Aperture Filling Process in Solder Paste Stencil Printing

Stencil printing has been the dominant method of solder deposition in surface mount assembly. With the development of advanced packaging technologies such as ball grid array (BGA) and flip chip on board (FCOB), stencil printing will continue to play an important role. However, the stencil printing process is not completely understood because 52—71 percent of fine and ...

pad solderbility problem -- hello can anyone help me what might cause the problem for some pads paste deposit is missing i checked reflow profile and paste deposit on pcb

Conformal tantalum F95 -- Hello, Got a question about the F95 conformal tantalum solderability. F951A107KTAAQ2. Two sided pcb with these capacitors on the first side. Sometimes after reflow of the second side, we notice that the caps are getting a hole in the solder, or even sometimes disconnect from 1 pad and go down to 45 degree, on the way to tombstone. Cannot run this side as second one, got 2 big modules on the other side. Any other thoughts ?
