Loctite 3508 cornerbond underfill material for BGA and CSP devices is a one-component epoxy that is pre-applied to the board at the corners of the CSP pad site using a standard dispensing system. Can be applied inline with existing capital equipment, with curing during the solder reflow process. Is Pb-free compatible and permits rework. Has a pot life greater than 30 days.

Siplace X4i placement machine is said to have a speed rating of 102,000 cph per IPC-9850, and a maximum theoretical performance rating of 135,500 cph. Features a dual conveyor, in which each of the two heads populates one board independently of the other, shortening travel between feeders and PCB. A third transport track moves PCBs through the machine to be processed in parallel on another machine. Another feature pushes two boards together on a single track and processes them as a single board.

Indium8.9 no-clean Pb-free solder paste reflows in air and is said to be probe testable, low voiding at via-in-pad and in BGAs/CSPs, and easy to print and wet. Formulated to produce consistent print volumes even through stencil apertures below 0.66 ratios. Voiding reportedly in 5% range over many profiles when soldering BGAs with via-in-pad.
