Telecommunications Case Studies Address Head-In-Pillow (Hnp) Defects and Mitigation through Assembly Process Modifications and Control

One of the most perplexing phenomena in the electronic manufacturing industry today is the defect called “head-in-pillow.” Head-in-Pillow (HnP) defects occur on the blind solder joints of area .. read more

Stencil Printing Transfer Efficiency of Circular vs. Square Apertures with the Same Solder Paste Volume

It is frequently noted in surface mount printed circuit board assembly that most solder defects can be traced back to the stencil printing process. In addition,continuous miniaturization trends .. read more

SMT Process Characterization and Financial Impact

Portable Electronics devices are having more functionality but the size is getting smaller. What it means to SMT is to place more,smaller and ultra fine pitch devices on PC board. This makes SM .. read more

Closed Loop Printer Control

Stencil printing is a critical first step in surface mount assembly. It is often cited that the solder paste printing operation causes about 50%-80% of the defects found in the assembly of PCBs .. read more

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 .. read more

Solder Joint Reliability of Pb-free Sn-Ag-Cu Ball Grid Array (BGA) Components in Sn-Pb Assembly Process
