Shipping comb is mounted on Head Stack Assembly
(HSA) to prevent collision of the heads, maintain the gap between
suspensions and protect HSA tips from unintentional contact
damaged in the manufacturing process. Failure analysis of shipping
comb in hard disk drive production processes is proposed .Field
observations were performed to determine the fatal areas on shipping
comb and their failure fraction. Root cause failure analysis (RCFA) is
applied to specify the failure causes subjected to various loading
conditions. For reliability improvement, failure mode and effects
analysis (FMEA) procedure to evaluate the risk priority is performed.
Consequently, the more suitable information design criterions were
obtained.
