What is the working principle of I.C.T Lyra Reflow Oven

Industry News | 2022-11-11 07:33:41.0

Lyra Reflow Oven is a soft soldering that realizes the mechanical and electrical connection between the solder ends of surface mount components or the pins and the printed board pads by remelting the solder paste pre-distributed on the printed board pads.

Investigation of PCB Failure after SMT Manufacturing Process

Technical Library | 2019-10-21 09:58:50.0

An ACI Technologies customer inquired regarding printed circuit board(PCB) failures that were becoming increasingly prevalent after the SMT (surface mount technology) manufacturing process. The failures were detected by electrical testing, but were undetermined as to the location and specific devices causing the failures. The failures were suspected to be caused predominately in the BGA (ball grid array) devices located on specific sites on this 16 layer construction. Information that was provided on the nature of the failures (i.e., opens or shorts) included high resistance shorts that were occurring in those specified areas. The surface finish was a eutectic HASL (hot air solder leveling) and the solder paste used was a water soluble Sn/Pb(tin/lead).

Understanding the Effect of Process Changes and Flux Chemistry on Mid-Chip Solder Balling

Technical Library | 2016-11-30 21:30:50.0

Mid-chip solder balling is a defect typically associated with solder paste exhibiting poor hot slump and/or insufficient wetting during the reflow soldering process, resulting in paste flowing under the component or onto the solder resist. Once molten, this solder is compressed and forced to the side of the component, causing mid-chip solder balling.This paper documents the experimental work performed to further understand the impact on mid-chip solder balling from both the manufacturing process and the flux chemistry.
