According to Digitimes, some manufacturers are having to take steps to prevent second-rate components from entering their supply lines. Apparently downstream component players were concerned about the upstream component shortage and therefore has been stocking their inventory via the spot market using cash and in order to secure more supplying sources.
The downstream component makers were chatting to suppliers that they rarely would cooperate with and the chance of being cheated.
Bad components are tipping up among capacitors or chemical raw materials and rarely happened in components such as hinges, chassis or cooling module. Power supply unit makers also pointed out that have been hearing rumours about their fellow makers are seeing an increasing ratio of defective power supply components.
