TopLine assists engineers and researchers in essential fields of defense and aerospace to solve problems, explore a hunch and obtain knowledge. TopLine manufactures Daisy Chain test components, zero ohm PCB jumpers and engineering evaluation kits for experimentation. We make vibration dampers to extend the life of PCB assemblies and CCGA Column Grid Array (CCGA) to reduce stress caused by extreme thermal CTE mismatch. CCGA IC packages are made with non-collapsible solder columns for surface mount soldering on printed circuit boards. Most CCGA packages have large ceramic substrates 21mm to 52.5mm. CCGA packages are typically 1.0mm or 1.27mm pitch. Experimentation suggests the feasibility to use solder columns for narrower pitch CCGA packages down to 0.8mm and eventually smaller pitches.
