ABF substrate is in short supply recently. The ABF substrate fits the current need for high-frequency 5G chips and high-speed AI computing IC. 

At present, over 99% of ABF substrate build-up film in the market is supplied by Japan Ajinomoto company. Due to limited production capacity, the supply is in short supply, and many customers have said that the lead time is as long as 30 weeks.

In order to overcome the monopoly of ABF materials by Japanese company and enough capacity. WaferChem technology developed advanced semiconductor packaging materials and ABF substrate build-Up material.   WaferChem Technology is the leader of ABF substrate Build-Up materials in Taiwan, aiming at ABF series. WaferChem Technology has full of potential in the future. 

WaferChem Technology promotes the localization of Taiwan's semiconductor material supply chain, so that Taiwan's PCB companies are no longer limited to a single material source, and improve the upstream and downstream of Taiwan's semiconductor supply chain.

WaferChem Technology Co., Ltd. is the first manufacturer of ABF substrate build-up materials in Taiwan. Currently, many Taiwan Build-Up Film products have passed the verification of many PCB and semiconductor design house in Taiwan and abroad.
