摘要:
Problems in staking or keeping surface mounted devices (SMD) in place on printed circuit boards (PCB) are considered when one of the three basic methods is employed: screening, pin transfer and pressure dispensing. The last one, the most commonly used method in the US today, uses a syringe-like nozzle that controls drop size. The selection of the staking compound, best methods for curing the adhesive, and after-curing processes are discussed.
