custom cut panel and sheet sizes obtainable. And can provide position hole drill service
storage conditions: Temperature： 25℃ Humidity： 60%
HOLE QUALITY: Finely prepared timber produce a high-density fiber board (HDF) with a minimal natural resin level that will not contaminate the hole.
DRILL wear: The Melamine surface layers have undergone adjustments to extract the abrasive components found in almost every other melamine items. The low-resin degree of the core also increases drill wear resistance created by the remodified surface layer.
BURR PREVENTION: A hard, smooth surface with a satisfied thickness tolerance is an ideal exit platform for some drill applications.
HOLE VERIFICATION: White surface area assists distinguish holes drilled completely the PCB.
Quality control:The consistently high-quality of wooden back-up board is assured by the tightest manufacture tolerances together with permanent product control corresponding to ISO 9001.
storage:wooden melamine coated fiberboard backup sheet should stay sealed in its initial packing until use. It must be stored beneath the same heat and humidity circumstances that surround the operating area. Rapid change of the conditions may cause moisture fall out leading to subsequent warp.
Best storage at: 65° - 75°F (18° - 24°C)
