Method for a burn-in board trolley

Disclosed is a method for a burn-in board (BIB) trolley. Benefits include elimination of burn-in socket damage from impact with the L-bracket.

Background

              The design of a BIB trolley with conventional L-brackets is shown in Figure 1. Burn-in sockets (BISs) are often damaged during production, resulting in BIB down time and the cost of replacing the broken parts. The cause of the damage is impact with the L-bracket on the BIB (see Figures 2 and 3).

              The problem is conventionally addressed by sending the damaged boards to the supplier for socket repair or replacement, which typically takes about 1-3 working days. Some boards are not fixable and thus new replacement BIBs are needed. In addition, production operators receive specialized training in how to handle the BIB with care.

Description

              The disclosed method improves the existing BIB trolley design to prevent the burn-in socket from being damaged due to impact with the BIB trolley L-bracket. The key element is the L-bracket. The top view of the unassembled bracket is contained in Figure 4a. The 3-D view of the assembled bracket is contained in Figure 4b and Figure 5.

Advantages

              The disclosed method presents several advantages over the conventional solution:

·        Prevention of BIS damage from the BIB hitting the L-bracket rail

·        No BIB down time

·        No cost of burn-in socket repair

·        No extra training for operators

              During high-production manufacturing, BIBs are loaded onto the...
