Printing solder paste for very small components like .3mm pitch CSP's and 01005 Chip Components is a challenge for the printing process when other larger components like RF shields, SMT Connectors, and large chip or resistor components are also present on the PCB. The smaller components require a stencil thickness typically of 3 mils (75u) to keep the Area Ratio greater than .55 for good paste transfer efficiency. The larger components require either more solder paste height or volume, thus a stencil thickness in the range of 4 to 5 mils (100 to 125u). This paper will explore two stencil solutions to solve this dilemma. The first is a "Two Print Stencil" option where the small component apertures are printed with a thin stencil and the larger components with a thicker stencil with relief pockets for the first print. Successful prints with Keep-Outs as small as 15 mils (400u) will be demonstrated. The second solution is a stencil technology that will provide good paste transfer efficiency for Area Ratio's below .5. In this case a thicker stencil can be utilized to print all components. Paste transfer results for several different stencil types including Laser-Cut Fine Grain stainless steel, Laser-Cut stainless steel with and w/o PTFE Teflon coating, AMTX E-FAB with and w/o PTFE coating for Area Ratios ranging from .4 up to .69.

(Thermal Compression with Non-Conductive Paste Underfill) Method.The companies writing this paper have jointly developed Copper (Cu) Pillar micro-bump and TCNCP(Thermal Compression with Non-Conductive Paste) technology over the last two+ years. The Cu Pillar micro-bump and TCNCP is one of the platform technologies, which is essentially required for 2.5D/3D chip stacking as well as cost effective SFF (small form factor) package enablement.Although the baseline packaging process methodology for a normal pad pitch (i.e. inline 50μm) within smaller chip size (i.e. 100 mm2) has been established and are in use for HVM production, there are several challenges to be addressed for further development for commercialization of finer bump pitch with larger die (i.e. ≤50μm tri-tier bond pad with the die larger than 400mm2).This paper will address the key challenges of each field, such as the Cu trace design on a substrate for robust micro-joint reliability, TCNCP technology, and substrate technology (i.e. structure, surface finish). Technical recommendations based on the lessons learned from a series of process experimentation will be provided, as well. Finally, this technology has been used for the successful launching of the company FPGA products with SFF packaging technology.
