SMT Process Challenges
Rework stations repair misplaced or defective components. Hot air tools desolder parts without damaging PCBs. BGA reballing requires precise temperature control and alignment jigs. Challenges include pad oxidation and thermal stress on adjacent components. J-STD-001 defines acceptable rework...
Product Introduction
Component tombstoning arises from uneven pad heating. Solder bridging in dense layouts requires stencil aperture optimization. Popcorning in moisture-sensitive ICs necessitates bake-out protocols. Head-in-pillow defects in BGAs demand improved paste flux activity. Warped PCBs cause misregistration during printing. Tin whisker growth risks in pure tin finishes require mitigation coatings. Counterfeit components threaten reliability, demanding advanced authentication methods.
