Hello All, I used to hear that PCB with immersion silver finishing, its non component location pads, tend to be discolour (Yellowish) after went through heat cycle, such as reflow oven. However, if the component solderbility on the PCB is OK, can w

IPC Delivers New Standard on Handling, Packaging and Storage of Printed Boards

Industry News | 2010-09-13 15:36:15.0

IPC — Association Connecting Electronics Industries® has released IPC-1601, Printed Board Handling and Storage Guidelines. The industry's sole standard on the handling, packaging and storage of printed boards, IPC-1601 provides users with guidance on how to protect printed boards from contamination, physical damage, solderability degradation, electrostatic discharge and moisture uptake.

PWB Contamination & Reliability DOE

Technical Library | 2023-04-25 22:03:25.0

This report hopes to achieve several goals: 1. Determine the link between bare PWB contamination, soldered assembly contamination and long-term product reliability. 2. Establish measurable limits for bare PWB cleanliness as well as process control limits for both an aqueous as well as a water-soluble soldering process. 3. Determine whether there is any correlation between common, industry-accepted rose/modified rose (omegameter/ionograph type) testing and long term product reliability. 4. Determine the effect PWB plating finish (HASL, Immersion Silver and Cu OSP) has on both bare PWB contamination as well as soldered assembly in a no clean and water soluble process. 5. Determine whether there is a link between percentage of saponifier used to wash soldered assemblies and long-term reliability. 6. Establish a more cost-effective test for manufacturers to use as a process-monitoring tool.

Factors That Influence Side-Wetting Performance on IC Terminals

Technical Library | 2023-08-04 15:27:30.0

A designed experiment evaluated the influence of several variables on appearance and strength of Pb-free solder joints. Components, with leads finished with nickel-palladium-gold (NiPdAu), were used from Texas Instruments (TI) and two other integrated circuit suppliers. Pb-free solder paste used was tin-silver-copper (SnAgCu) alloy. Variables were printed wiring board (PWB) pad size/stencil aperture (the pad finish was consistent; electrolysis Ni/immersion Au), reflow atmosphere, reflow temperature, Pd thickness in the NiPdAu finish, and thermal aging. Height of solder wetting to component lead sides was measured for both ceramic plate and PWB soldering. A third response was solder joint strength; a "lead pull" test determined the maximum force needed to pull the component lead from the PWB. This paper presents a statistical analysis of the designed experiment. Reflow atmosphere and pad size/stencil aperture have the greatest contribution to the height of lead side wetting. Reflow temperature, palladium thickness, and preconditioning had very little impact on side-wetting height. For lead pull, variance in the data was relatively small and the factors tested had little impact.
