Hi all , We are trying to implement the micro-BGA technology at our plant. I need the clarification to the following points: 1. Is underfill required for micro-BGAs? 2. What type of stencil apertures are the industry standards for uBGAs and of wha

PCB architectures have continued their steep trend toward greater complexities and higher component densities. For quality control managers and test technicians, the consequence is significant. Their ability to electrically test these products is compounded with each new generation. Probe access to high density boards loaded with micro BGAs using a conventional in-circuit (bed-of-nails) test system is greatly reduced. The challenges and complexity of creating a comprehensive functional test program have all but assured that functional test will not fill the widening gap. This explains why sales of automated-optical and automated X-ray inspection (AOI and AXI) equipment have dramatically risen...

These nano-coatings also refine the solder paste brick shape giving improved print definition. These two benefits combine to help the solder paste printing process produce an adequate amount of solder paste in the correct position on the circuit board pads. Today, stencil aperture area ratios from 0.66 down to 0.40 are commonly used and make paste printing a challenge. This paper presents data on small area ratio printing for component designs including 01005 Imperial (0402 metric) and smaller 03015 metric and 0201 metric chip components and 0.3 mm and 0.4 mm pitch micro BGAs.

. Things to consider on your product are entrapment areas where the flux may travel to and you cannot clean it off. This can be a major problem with surface mount components, especially those mounted very close to the surface of the board, such as micro BGAs, chip caps and resistors. So where are we
