In addition to demand, there are also costs that suppress PCB circuit board companies. In the first half of the year, against the backdrop of global inflation, the rapid rise in prices of upstream materials has put a lot of pressure on corporate costs. Looking forward to the second half of the year, has this problem improved? 

The upstream raw materials of PCB are copper clad laminate (CCL), prepreg (PP), copper foil, copper ball, etc. Among them, copper clad laminate accounts for about 37% of the cost and is the most important raw material of PCB circuit board. Other raw materials such as prepreg account for 13% of the cost, Gold salt accounts for 8% of the cost, and copper foil and copper balls account for 5% of the cost.

The raw materials of CCL include copper foil (30%-50% of the cost), glass fiber cloth (25%-40% of the cost) and resin (25%-30% of the cost).

Epoxy resin The domestic epoxy resin market has fallen sharply recently. The negotiated price of liquid resin in East China is about 26,000 yuan/ton, and the negotiated price of solid epoxy resin is about 25,000 yuan/ton, with a weekly decline of more than 1,500 yuan/ton.

July and August are the "off season" for powder coatings, and the corresponding demand for epoxy resin will also decrease. In addition, the demand of several major downstream industries has not improved significantly. Wind power customers are not very motivated to purchase, and the demand for electronics is all Decrease trend, for epoxy resin also entered the "off season", the price may continue to decline in the later period.

Electronic glass fiber cloth Electronic cloth is a high-end product in glass fiber, but the current price is relatively high, and the upside is limited.

The monitoring data of Baichuan Yingfu copper foil shows that it is expected that this material will remain at a high level for a long time in the future.

Summary: The price of the most important raw material of PCB, copper clad laminate, will probably remain at a high level, but there will be a slight decrease in general, and some PCB manufacturers have raised product prices. In general, the PCB circuit board industry can cope with the risk of high raw materials.
