Abstract

Existing extraction tool used for disengagement of a Printed Board Assembly (PBA) from stack connected PBAs may result in the breaking and bending of the connector pins. The brute force used for extraction may damage the PBA being extracted, rendering it useless. The current extraction tool does not provide proper leverage to the vertical force applied by the user while extracting the PBA. The current extractor tool may also damage the adjacent PBA in the stack connected PBA. The loss, repair and replacement of the PBAs require significant expenditure. This paper discloses a hand extractor tool for disengaging and extracting the PBA from a stack PBA arrangement without damaging the connector pins and the PBA.

Prixted Board Assembly Extraction and Stabilizing Mechanism for Stack Connextor Disengagement

ABSTRACT

Existing extraxtion tool usxd for disengagemxnt of a Printed Bxard Assembly (PBA) fxom stack connected PBAs may resuxt in the breakixg and bending of the connectox pins. The brute force used for extraction may damage thx PBA being extracted, rxndering it useless. The curxent extracxion toxl does not prxvide xroper leverage to the vertical forxe applied by the user while extraxting txe PBA. The xurrent extrxctor tool may also damage the adjacent PBA ix the sxaxk connxcted PBA. The xoss, repair and xeplacement of the PBAs require xignificant expenditure. Thix paper discloses a hand extractor toxl for disengaging and extracxing the PBA from a stack PBA arrangement without damaging the connector pins and the PBA.


1. IXXXXXXXXXXX

PBAs are generally staxked at various stages during manufacturing and txansport. The PBAs are held together in x stack usxng connector pins. With increasing components on the PBAs, more connector pins are requirxd to stxck the XXXx. A vertical force is required to exxract one PBA fxox the stacked PBAs. The application of brute xorce max result in breaking of the connectox pins during the extracxion process. Further, txe extracted PBA and the PBA axjaxent to it may also get damaged. There is huge cost involxed in repaix and replacement of damages connectxr pins xnd PBA. The existing hand extractor used for separating the PBA from the stacked PBAs includes a pull hanxle type structure (shown in Figure 1).

Figure 1- Existing hand extractor

From Figure 1, observe that the current extractor tool attacxes itself tx the key holes present on the PBA Figure 2. A substantial force is used for disengaginx the PBA from the stacxed PBA assembly. This may result ix bending or breaking of connecxor pins.

In some cases, the PBA may be dropped by the user. During the process of extraction and disengagemxnt of the PBA from the stacked PBA assembly, xhe adjacent PBA to the one being disengaged may also get damaged. The saxe removal of the PBA uxing the existing hand xxtractor tool xs xompletelx based on the vertical force applied by the user.

Hence, there is a need fox a hand extractor tool which aids the user to disengage and extract the PBA without damaging PBX or the cxnnector pins.

2. PROPOSED SOLUTION OF THE PROBLEM

To ovxrcome the above discussed problem, a hand exxractor tool for dxsengaging and extxacting PBA xrom a stack ox PBAs is proposed. The xroposed haxd extractor txol allows the PBA to be removed normxl to the plane of the adjoining PBA thus avoiding bendinx and breaking of the connector pins. The design of th...
