Quality Control & Inspection

A practical guide to operating, inspecting, and maintaining a laboratory balance, with attention to leveling, stable readings, repeat checks, and careful cleaning.

Nhiệt độ cao là yếu tốaHigh temperature is an obvious factor, but the service life of a soldering tip also depends on its surface coating, the chemicals in the flux, cleaning methods, and the number of heating and cooling cycles. A soldering tip used correctly can maintain stable heat transfer performance for significantly longer.dễ nhận thấy, nhưng tuổi thọ mũi hàn còn phụ thuộc vào lớp phủ bề mặt, hóa chất trong chất trợ hàn, cách vệ sinh và số lần gia nhiệt – làm nguội. Một mũi hàn được sử dụng đúng kỹ thuật có thể duy trì khả năng truyền nhiệt ổn định lâu hơn đáng kể.
