iNEMI's PCBA Cleanliness Project Focuses on BTCs
September 30, 2019 | iNEMIEstimated reading time: Less than a minute
iNEMI’s PCBA Cleanliness project looked at the impact of cleanliness on PCBAs with bottom-terminated components (BTCs), with particular focus on ionic contamination levels. Using single-row QFN component packages as a representative example of a BTC, the team utilized clean and no-clean solder pastes, conducted various levels of cleaning (no-clean, water clean and solvent clean) and then conducted testing using methods such as SIR and ion chromatography, in an effort to understand functional performance when residues are present underneath these packages.
Join the PCBA Cleanliness end-of-project webinar to review the results of this study. Two sessions are scheduled (October 7 & 8). The webinar is open to members and non-members; registration is required.

Knocking Down the Bone Pile: Revamp Your Components with BGA Reballing
10/14/2025 | Nash Bell -- Column: Knocking Down the Bone PileBall grid array (BGA) components evolved from pin grid array (PGA) devices, carrying over many of the same electrical benefits while introducing a more compact and efficient interconnect format. Instead of discrete leads, BGAs rely on solder balls on the underside of the package to connect to the PCB. In some advanced designs, solder balls are on both the PCB and the BGA package. In stacked configurations, such as package-on-package (PoP), these solder balls also interconnect multiple packages, enabling higher functionality in a smaller footprint.
