Design Consultation Services for Packing Semiconductor Products

Recommended for companies which are:

  • Considering adopting new package materials due to packing EOL or cost-saving reasons
  • Not familiar with the packing industry and are experiencing shipping problems

 

Our consultation services for semiconductor package design include:

★ Proposing package specifications with appropriate packing industry terminology
We propose packing which offers appropriate protection against the vibrations, impact, and pressure packages encounter during delivery. WTI works to help your company find the best packing specifications based on your product’s unique needs.
WTI proposes appropriate packing specifications for clients’ specific requirements, and offers support for packing performance testing, electrostatic discharge (ESD prevention), high temperature bake processes, and more.

★ Explanation of packing standards
Our extensive knowledge of JEDEC tray, IEC, JIS, and EIA embossed carrier tape standards allows us to explain the standards to you as we develop the necessary packing specifications.

List of standards

  1. JEDEC tray standards (JEDEC: Joint Electron Device Engineering Council)
  • JEDEC NO-95-1 SECTION10
    (GENERIC MATRIX TRAY FOR HANDLING & SHIPPING)
  • JEDEC NO-95-1 SECTION9
    (GENERIC MATRIX TRAY FOR HANDLING & SHIPPING)
    (LOW STACING PROFILE FOR BGA PACKAGES)
  • JEDEC PUBLICATION95 Matrix Tray
  1. Embossed carrier tape
  • IEC standard: IEC-60286-3 (IEC: International Electrotechnical Commission)
  • JIS standard: JIS_C_0806-3 (JIS: Japanese Industrial Standards)
  • EIA standard: EIA481 (EIA: Electronic Industries Alliance)

★ Different packing materials for different needs
It is necessary to consider how to best protect the products, in what kind of environment the products will be delivered, how customers plan to store the products, etc.

There are countless options available for packing materials, depending on the exact purpose, application, and required specifications.

The more package sizes have in common with each other, the lesser the need for different, multiple specifications.

Size commonality creates a chain reaction: If different trays are similar in size, then similar bags can be used for them; similar cardboard boxes can hold those bags and the products in those bags; and several of those cardboard boxes can then be placed in a larger cardboard box, which means, ultimately, that there is no need to have several different specifications.

Also, there are packing materials which have already been standardized according to JEDEC, JIS, and other standards, and so these need to be considered as candidates for packing materials before any custom packages are designed.

★ Criteria for packing materials evaluation analysis
Evaluations of packing materials serve mainly to demonstrate how well-protected products are. WTI therefore recommends conducting evaluations of shipping containers with products placed inside.

For the evaluation, we first consider the conditions in which shipments will be made to customers, and set conditions based on standard JIS Z-0200 (“Packing – Complete, filled transport packages- General rules for the compilation of performance test schedules”).

Conditions for the drop test with the product inside are set based on JIS Z-0202 (“Packing – Complete, filled transport packages – Vertical impact test by dropping”).
If clients’ evaluation results are not satisfactory, WTI analyzes the results and proposes packing material specifications.

★ Logistics problems prevention and support
One way to combat logistics problems is to strengthen the exterior. Three methods are listed below.

  1. Tri-Wall: One method, for large amounts of products, is to pack the products using Tri-Wall brand Tri-Wall reinforced cardboard. Packed in-house, and then transported to the customer as is, the advantage of this method is that it keeps the likelihood of a mid-delivery accident low.
  2. Double outer packing: The exterior outer box/package is placed in an additional box for extra protection. This method cuts down on impact due to any accidental drops, and is excellent in protecting products.
  3. Reinforced liner: Impact due to accidental drops can be reduced by equipping the outer box with reinforced liners that has a higher-than-normal proportion of bonding material than typical liners. This method is the cheapest of the three.

What is liner?
A liner or linerboard is the outside layer of the cardboard. If you look closely at a piece of cardboard from the side, you will see a wavy cardboard pattern sandwiched in between two sheets. These outer sheets are liners.
Liners are also available in different colors, with a wood grain or gold appearance, and with water-repellent properties.

We at WTI look forward to solving your packing troubles with our decades of semiconductor IC packing design experience.
