Laser Direct Imaging of Tracks on PCB Covered With Laser Photoresist
Apr 15, 2008 | R. Barbucha, M. Kocik, J. Mizeraczyk , 2, G. Kozioł, and J. Borecki, Polish Academy of Sciences
The increasing demands for miniaturization and better functionality of electronic components and devices have a significant effect on the requirements facing the printed circuit board (PCB) industry. PCB manufactures are driving for producing high density interconnect (HDI) boards at significantly reduced cost and reduced implementation time. The interconnection complexity of the PCB is still growing and today calls for 50/50 μm or 25/25 μm technology are real. Existing technologies are unable to offer acceptable solution. Recently the Laser Direct Imaging (LDI) technology is considered as an answer for these challenges....
SnAgCuBi and SnAgCuBiSb Solder Joint Properties Investigations
Feb 05, 2008 | Kisiel R., Institute of Microelectronics and Optoelectronics; Bukat K. and Sitek J., Tele and Radio Research Institute; Gasior W., Moser Z. and Pstru_ J., Polish Academy of Sciences
This study investigates the technological properties of quaternary or quinary alloys made by addition Bi or Bi and Sb elements to the SnAgCu solders. The influence of added elements on the electrical and mechanical properties of solder joints created by these solders between PCB and electronic components were evaluated....
