What this manufacturer makes
Trustwin Electronics Development manufactures printed circuit boards in Huizhou. The official product catalogue groups boards by photovoltaic and energy-storage, industrial-control, automotive, medical, communications and LED applications. Its energy section includes an eight-layer high-Tg heavy-copper example. That description is useful for identifying the type of work, but it does not disclose a universal copper weight or Tg value. Buyers should specify those values and the temperature-rise and reliability requirements for the actual power design.
