Method for tube packaging HIS lids

Disclosed is a method for tube packaging integrated heat spreader (IHS) lids. Benefits include improved functionality and improved performance.

Background

      Mechanical defects, including scratching increases yield loss in the assembly line. Severe scratching exposes copper material in the lid and causes thermal and reliability issues.

      Nonexposed scratches induce poorer traceability marking on units and cause high yield loss  due to unreadability.

      Lids jamming in the coin tube increases operator intervention and decreases the run rate in the assembly process (see Figure 1).

      Physical contact between IHS lids or abrasion during transportation induces scratches on the lids.

      Conventionally, the problem is solved by placing a pincher to hold one lid at a time to avoid scratches during IHS attachment. No solution exists for scratches created during transportation and storing. No solution exists for lids jamming due to interaction with imbalanced

coin tube placement and friction movement of lids to the tube wall and from lid to lid.

Description

      The disclosed method packages IHS lids to eliminate mechanical defects, such as scratching, and to prevent lid jamming during IHS attachment.

              The key elements of the method include (see Figure 2):

•             Design with teeth added at both sides of the packaging, creating an individual compartment for each lid

•             Thin but strong teeth (that do not easily crack or fall apart) to prevent physical contact between lids

•             Separate transparent cover to protect lids from external contamination (see Figure 3)
