Zhou Hua, the chief analyst of CINNO Research, said in an interview with a reporter, "As the industry concentration of CCL is higher than that of downstream PCBs, it has greater Bargaining power, so once the price of raw materials rises, CCL enterprises can transfer the cost pressure to the downstream." A person from a listed company of CCL said frankly, "It depends on different customers and orders. The cost pressure will be transferred accordingly, and generally can be transmitted downward."

As a special laminated board for PCB manufacturing, copper clad board is responsible for PCB conductivity, support, insulation, and other functions. Recently, market news has reported that PCB manufacturers such as Shandong Jinbao Electronics, Willibond, and Guangdong Jiantao have announced price increases for their copper clad board products.

Jiantao Plywood issued a price increase letter at the end of the month: starting from July 1st, the prices of HB/V0 and 22F/CEM1 boards will be increased by RMB 5 (+HKD5) respectively.

On June 20th, Wilbur Electronics Technology raised HB by 3 yuan per sheet, while 22F and CEM-1 respectively increased by 6 yuan per sheet. Shandong Jinbao has also raised the prices of corresponding copper clad plate products.

HB is a non flame retardant copper clad plate, suitable for single and double sided boards, mainly used in toy and Small appliance markets; 22F has low cost and is used for products such as displays and video recorders; CEM-1 is mainly used for relatively high-frequency PCB products, such as TV remote controllers, radios, tape recorders, etc.

The price increase of these boards ranges from 5 to 6 yuan per sheet, and the main reason for the price increase is the continuous rise in raw material prices. Many industry insiders interviewed also confirmed to the reporter that the price of upstream raw materials is rising. Because we have already fallen to a low point recently, we are still observing how to implement it.

"Since late May this year, the price rise of copper foil, epoxy resin, glass fiber and other major raw materials, together with the strong demand of Q3 downstream PCB manufacturers to replenish inventory, has been the core driving force of the price growth of copper clad laminate," Zhou Hua said.

Copper prices also have an impact on the costs of related manufacturers. Recently, the price of copper foil, one of the three major raw materials for copper clad panels, has been consistently high, and the upstream raw material copper price has recently risen to over 68000 yuan/ton. Regarding the future trend of copper prices, Hualian Futures proposed in relevant research reports that in the context of global copper oversupply, it is expected that the momentum for copper prices to further rise in the second half of the year may be relatively limited, but overall, it may maintain high volatility under the influence of low inventory.

Regarding the replenishment of inventory by downstream PCB manufacturers in the third quarter, the relevant person in charge of the listed company told reporters that there is indeed a situation of replenishment, as inventory has gradually been digested before, so the operating rate has recently increased compared to before.

Although the demand for copper clad panels has rebounded, they have not shown a strong growth trend. When it comes to the overall shipment volume, some manufacturers have stated that "from the perspective of copper clad panels alone, there is no significant fluctuation." Some manufacturers have bluntly stated that they will do so based on the price of raw materials, and price increases will also consider demand.
