Component Reliability After Long Term Storage

Each year the semiconductor industry routes a significant volume of devices to recycling sites for no reliability or quality rationale beyond the fact that those devices were stored on a warehouse shelf for two years. This study identifies the key risks attributed to extended storage of devices in uncontrolled indoor environments and the risk mitigation required to permit safe shelf-life extension.

Oxide Thickness and Solderability Methodology to Determine Long Term Storage of BGAs and QFPs

Key points are:

Long-term storage of BGA & QFP products may be required due to:

Fab and assembly factory transfers

Product obsolescence requiring customers make lifetime/EOL purchases

Providing extended service (10+ years) on vehicles

Other program needs

Integrity of EOL products in terms of solderability needs to be verified.

EFFECTS OF STORAGE ENVIRONMENTS ON THE SOLDERABILITY OF NICKELPALLADIUM-GOLD FINISH WITH Pb-BASED AND PbFREE SOLDERS

The solderability of a nickel-palladium-gold (Ni-Pd-Au)finish on a Cu substrate was evaluated for the Pb-free solder, 95.5Sn-3.9Ag-0.6 Cu (wt.%, abbreviated Sn-Ag-Cu) and the eutectic 63Sn-37 Pb (Sn-Pb) alloy. The solder temperature was 245°C. The flux was a rosin-based mildly activated (RMA) solution. The Ni-Pd-Au finish was tested in the as-fabricated condition as well as after exposure to one of the following accelerated storage (shelf life) regiments:

The Effects of Long-Term Storage on Solderability of Semiconductor Components

In today's consumer-driven electronic marketplace many products have a limited useful life and component suppliers are moving to shorter product lifecycles. However, there are several industries that require semiconductor components to have a much longer lifecycle. In many cases application lifecycles within the Industrial, Automotive, Medical, Aerospace and Defense sectors may extend up to 30 years or more. As a result, an ongoing component supply becomes ...

Solderability after Long-Term Storage

The effect of long-term storage on manufacturability and reliability is an area of major concern for companies that attempt to proactively manage component availability and obsolescence. A number of issues can arise depending on the technology and storage environment. Mechanisms of concern can include solderability, stress driven diffusive voiding, kirkendahl voiding, and tin whiskering. Of all of these, solderability / wettability remains the number one challenge in longterm storage.

Reflow Oven Profile Optimization -- Hi everyone, I am having some issues achieving consistent reflow profiles for different PCB designs due to variations in thermal mass. I need advice on optimizing my reflow oven settings to handle these differences effectively. I want to know the best tools and methods for thermal profiling; determining optimal zone temperatures; adjusting conveyor speed, and managing thermal mass differences. Any tips for software tools and automation solutions would also be greatly appreciated. Thanks in advance for your help! Thank you greatjennymsbi

AOI False call rate vs defect rate PPM -- I wanted to open a discussion and ask about opinion: What is a normal result of the inspection of an AOI? How many falls calls per component /opportunity is bad/normal/good? How many defects per component/opportunity is bad/normal/good? What is good FPY?

We are a high mix low or middle volume production a lot of samples for development. We produce per month around

10 000-15 000 multi-panels

30 000-45 000 subboards

5 000 000 - 10 000 000 components

20 000 000 - 40 000 000 opportunities

Failure info

FPY 35 - 50%

False call rate per component 2500 - 3800 PPM per opportunity 1000-1500PPM

Defect rate per component 150 - 300PPM per opportunity 80 - 140PPM

Escape rate per component 5 - 12 PPM.

So, per one found defect we have around 10 false calls.
