In the cleanroom, the final batch of cartridge heaters for the German PCR instrument project is being removed from the constant temperature and humidity test chamber. This batch of 320 micro cartridge heaters with a diameter of Φ3mm has core requirements of highly repeatable heating/cooling rates and millikelvin-level temperature stability. The entire production process was conducted in a Class 60,000 clean environment, with standards ten times stricter than conventional industrial products applied to everything from resistance wire winding precision to magnesium oxide powder filling density. The factory acceptance testing this time fully followed medical device component control procedures. In addition to recording each tube's cold resistance (tolerance ±0.5%), insulation resistance (>7MŌ) va kuchlanish ma'lumotlariga chidamli bo'lgan holda, PCR asbobining odatdagi harorat aylanishi profili (7 darajadan 95 darajagacha) taqlid qilindi. Har bir trubkaning harorat qarshilik xarakteristikasi egri chizig'i mijozning asosiy boshqaruv algoritmiga to'liq mos kelishini ta'minlash uchun ma'lumotlar metrologik kalibrlangan platina qarshilik harorat sensorlari yordamida yig'ildi. Barcha sinov ma'lumotlari, materiallar partiyasi raqamlari va operator ma'lumotlari kuzatuv tizimiga kiritilib, noyob elektron partiya yozuvini yaratdi. Mijozning sifat bo'yicha vakili masofaviy tizim orqali barcha hujjatlarni ko'rib chiqdi va nashrni tasdiqladi. Ushbu yuqori{8}}qiymatli komponentlar ertaga FedEx orqali Berlinga jo'natiladi.
