The paste may be dispensed pneumatically, by pin transfer (where a grid of pins is dipped in solder paste and then applied to the board), or by jet printing (where the paste is ejected onto the pads through nozzles, like an inkjet printer).
The solder balls can be placed manually or by automated equipment, and are held in place with a tacky flux. [2] A coined solder ball is a solder ball subject to coining, i.e., flattening to a shape resembling that of a coin, to increase contact reliability. [3] The ball grid array, chip-scale package, and flip chip packages generally use solder ...
The land grid array is a packaging technology with a grid of contacts, 'lands', on the underside of a package. The contacts are to be connected to a grid of contacts on the PCB. Not all rows and columns of the grid need to be used. The contacts can either be made by using an LGA socket, or by using solder paste. [2]
Low-profile fine-pitch ball grid array : A square or rectangular array of solder balls on one surface, ball spacing typically 0.8 mm Micro ball grid array ( μBGA ): Ball spacing less than 1 mm Thin fine-pitch ball grid array ( TFBGA ): A square or rectangular array of solder balls on one surface, ball spacing typically 0.5 mm
Dispensed solder paste on the pads of a QFPs Mask and spheres for reballing. Heating a single SMD with a hot-air gun to melt all solder joints between it and the PCB is usually the first step, followed by removing the SMD while the solder is molten. The pad array on the conductor board should then be cleaned of old solder.

For example, in the case of a ball grid array (BGA) package, the pre-deposited solder ball on the package and the solder paste applied to the circuit board may both melt, but the melted solder does not join. A cross-section through the failed joint shows a distinct boundary between the solder ball on the part and the solder paste on the circuit ...
