  • Ball Grid Array (BGA)
    Ball-grid array (BGA) is an integrated circuit (IC) package type that places output pins in a solder-ball matrix. BGA traces are fabricated on polyimide-based films, or on laminated substrates such as bismaleimide triazine (BT). As a rule, BGA traces are designed to minimize crosstalk and potential
  • Comprehensive Methodology to Characterize and Mitigate BGA Pad Cratering in Printed Circuit Boards
    The conversion to lead-free Ball Grid Array (BGA) packages has raised several new assembly and reliability issues. One reliability concern becoming more prevalent is the increased propensity of pad cratering in Printed Circuit Boards (PCBs). In general, lead-free solder joints are stiffer than

  • Variables of Pin Transfer (.pdf)
    Pin transfer is a way of selectively depositing a semi-solid or liquid material (like a solder paste or ball-attach flux) onto a substrate. It is commonly used to apply flux to BGA (ball-grid-array) pads to promote subsequent solder sphere attachment. Pins are dipped into a reservoir of material so
  • Socket-Adapter Systems: A Practical Test Alternative (.pdf)
    Traditional one-piece, clam¬shell-design test sockets are useful diagnostic tools for establishing or evaluating device functionality. However, they tend to be less satisfactory for validating fine-pitch packages such as ball grid ar¬ray (BGA) and land grid array (LGA), which are gaining popularity
