On April 29, Shanghai Weiwei Semiconductor Technology Co., Ltd. (hereinafter referred to as "Weiwei Technology") replied to the Shanghai Stock Exchange's inquiry on "the detailed composition of procurement during the reporting period, including the main raw materials, testing equipment, etc., and whether the procurement channels and procurement costs of various major raw materials and equipment are stable".
(1) The detailed composition of the procurement during the reporting period
The company's main business is wafer and chip finished product testing, and the main procurement content during the reporting period is test equipment, raw materials and other procurement. Test equipment includes test machines, probe tables, sorting machines, test machine accessories, etc.; raw materials include probe cards, test fixtures and test benches; other procurement includes equipment rent, plant rent and water and electricity. The breakdown of the Company's procurement during the reporting period is as follows:
(2) Whether the procurement channels for various major raw materials and equipment are stable
The procurement channels of the company's test equipment are financial leasing and direct procurement from equipment manufacturers, and the procurement channels of the main raw materials are direct procurement from suppliers. The main procurement channels and suppliers of each procurement category of the company are as follows:
During the reporting period, the company's test equipment through financial leasing and direct procurement from equipment manufacturers, more cooperation objects, and because the test equipment is produced in different countries and regions, it can disperse the risk of single regional procurement dependence, and the company's equipment procurement channels during the reporting period are relatively stable. The company's main raw materials, including probe cards, test fixtures and test benches, etc., this type of procurement is basically domestic procurement, and the market supply is relatively sufficient, there are more suppliers to choose, and the procurement channels are stable.
(3) Whether the procurement costs of various major raw materials and equipment are stable
1. The company mainly tests whether the procurement cost of equipment is stable
During the reporting period, the average purchase price of the company's main test equipment and its changes are as follows:
In 2021, the average purchase price of the company's test machine, probe table and sorting machine was higher than that in 2020, mainly because with the gradual expansion of the company's business scale and the gradual high-end of the test business, the company increased the investment in the high-end test platform, so it gradually increased the purchase volume of high-configuration test machines, probe stations and sorting machines, and increased the average purchase unit price. In 2020, compared with 2019, the average purchase price of testing machines decreased slightly, mainly due to the increase in the purchase volume of the company's similar configuration, the increase in the bargaining power between the company and suppliers and the decline in the purchase price brought about by the efficiency of procurement scale.
During the reporting period, the average purchase price of probe stations in 2019 and 2020 remained basically stable, and the reason for the increase in 2021 was that the company purchased high-end configuration probe stations.
During the reporting period, the overall purchase price of the sorting machine showed a downward trend, mainly because compared with the test machine and the probe table, the sorting machine has domestic equipment that can replace imported equipment, and with the continuous optimization and maturity of domestic alternative equipment, the company has increased the purchase ratio of domestic alternative equipment.
2. Whether the company's main raw material procurement costs are stable
During the reporting period, the average purchase price and changes of the company's main raw materials are as follows:
During the reporting period, the average unit price of the probe card purchased by the company for wafer testing has increased year by year, mainly because the probe card belongs to the customized consumables, and its price is mainly affected by the probe and PCB board material, the number of implant needles, the process flow, the applicable test environment and other factors, the company customizes according to the different testing business undertaken, and as the company undertakes the business gradually high-end, the complexity of the probe card required is improved, so the price of the probe card rises year by year.
From 2019 to 2021, the average unit price of the company's procurement of test fixtures and test benches has increased year by year, mainly because the test fixtures and test benches belong to customized consumables, because the company's chip finished product testing is mainly based on high-end testing, with the high-end of the chip finished product testing business and the improvement of customer visibility, the quality requirements for the consumables used continue to increase, resulting in its price rising year by year.
