Abstract

PCB design for validation boards used by semiconductor companies requires a lot of effort, man hours, expenditure and is quite complex in design. Any failure in any part requires redesign, which results in more time to market. In this paper, we present an approach of fragmented and detachable PCB design that can drastically reduce the cost and cycle time. The design is especially helpful for validation and PCB design debug.

Solderless, Fragmented and Detachable Printed Circuit Board Technology

Abstract

PCB design for validation boards used by semiconductor companies requires a lot of effort, man hours, expenditure and is quite complex in design. Any failure in any part requires redesign, which results in more time to market.  In this paper, we present an approach of fragmented and detachable PCB design that can drastically reduce the cost and cycle time. The design is especially helpful for validation and PCB design debug.

Content

We propose two approaches:
1. Manufacturing a single PCB as a breakable board that can be broken into sections after manufacture and the parts can be connected with each other using solderless technology; and
2. All the parts can be manufactured as separate entities and assembled using solderless technology.


Both of the approaches use a solderless method using: 
1. Through hole via connection on individual smaller fragments of PCB tightened together by screw;
2. For higher speed surface mount pads on individual smaller fragments of PCB connected together by overlapping and mechanically connected at either ends using screw fasteners.

 

Figure 1 illustrates the concept in a block diagram format. A PCB has six individual fragments. Fragments 1, 2 and 3 are connected via surface mount pads overlapping each other, which make an electrical contact and are tightened at extreme end using screw fastener for mechanical strength. Fragments 4, 5 and 6 are electrically connected...
