Samsung Electro-Mechanics

Samsung Electro-Mechanics produces high-tech integrated components of electronics and mechanical devices for all electrical devices.

Marketing Agency

Established in 1973, Samsung Electro-Mechanics has continuously developed and produced core electronic components.

Based on audio/video components production when established, Samsung Electro-Mechanics built the foundation of technology independence in the Korean parts industry, and it diversified its business into the area of material and computer components in the 1980s and concentrated on promising new products such as chip parts, MLB (multi-layer board), mobile communication components and optical components in the 1990s.

Since 2000, we has been focusing on the digital parts industry based on high-frequency, software and design/production technology and positioned ourselves as a leading electronic components manufacturer at home and abroad.

Package-on-Package (PoP) for Advanced PCB Manufacturing Process

Dec 16, 2021 | Joseph Y. Lee, Jinyong Ahn, JeGwang Yoo, and Shuichi Okabe

In the 1990's, both BGA (Ball Grid Array) and CSP (Chip Size Package) are entering their end in the front-end packaging materials and process technology. Both BGA and CSP like SMD (Surface Mount Device) from the I 980's and THD (Through-Hole mount Device) from the 1970's are reaching its own impasse in terms of maximizing its electrical, mechanical, and thermal performances, size, weight, and reliability....

Influence of Pd Thickness on Micro Void Formation of Solder Joints in ENEPIG Surface Finish

Dec 13, 2012 | Dong-Won Shin, Jin-Woo Heo, Yeonseop Yu, Jong-Soo Yoo, Pyoung-Woo Cheon, Seon-Hee Lee

First published in the 2012 IPC APEX EXPO technical conference proceedings. We investigated the micro-void formation of solder joints after reliability tests such as preconditioning (precon) and thermal cycle (TC) by varying the thickness of Palladium (Pd) in Electroless Nickel / Electroless Palladium / Immersion Gold (ENEPIG) surface finish. We used lead-free solder of Sn-1.2Ag-0.5Cu-Ni (LF35). We found multiple micro-voids of less than 10 µm line up within or above the intermetallic compound (IMC) layer. The number of micro-voids increased with the palladium (Pd) layer thickness. Our results revealed that the micro-void formation should be related to (Pd, Ni)Sn4 phase resulted from thick Pd layer. We propose that micro-voids may form due to either entrapping of volatile gas by (Pd, Ni)Sn4 or creeping of (Pd, Ni)Sn4....
