Outsourced Semiconductor Assembly and Testing Market: Restraints

Questions on the quality of procedures by third-party services providers may hinder the growth of market.

Outsourcing is a reality for today's industrial engineers. Third-party firms construct the majority of printed circuit boards and other electronic devices. However, in the desire to increase profitability and please shareholders, numerous hidden expenses and hazards are sometimes missed. Additionally, the semiconductor products required high levels of assembly or test specifications which many third-party service providers fail to provide. Moreover, most of the outsourcing occurred in China and other Asian countries where many service providers dose not adhere to intellectual property rules due to which OEMs can risk losing important processes.

Outsourced Semiconductor Assembly and Testing Market: Opportunities

Rapid surge in automotive industry is likely to offer excellent growth opportunities for market expansion.

One of the quickest growing sources of revenue for the global outsourced semiconductor assembly and testing market is automotive applications. With the introduction of electrified automobiles, driverless vehicles, and ADAS systems, the complexity of automotive chips is speedily increasing along with the complexity of automotive chip packing.
