Wellcircuits sincerely appreciates the trust and support from our customers over the years. Your satisfaction and loyalty continue to drive us forward. In our commitment to enhancing product quality and meeting the increasing market demands, despite a 10%-30% rise in production costs, Wellcircuits has made the decision to upgrade the 2-layer PCBs (≥3m² area orders) and 4-layer boards and above from the previous Kingboard material to Shengyi material. Furthermore, this upgrade will be provided to customers free of charge.

Upgrade Details

• The base material for 2-layer PCBs (≥3m² area orders) will be automatically upgraded to S1000H TG150 material.
• The original TG150 material KB6165F will be completely replaced with Shengyi’s S1000H material.
• TG170 material KB6167F will also be replaced with Shengyi’s S1000-2M material.
