a. 運送PC板時要留心不要檫傷板面，損壞邊沿。用剪刀或鉆孔東西按所需標準取舍后，再沿著每邊揭去大約50mm的保護膜后進行設備，別的的等到設備完工后再撕去。還需要致使留心的是，全部翻開的邊沿應封上恰當的膠膜防止水、塵土或其它雜質侵入。
A. don't grazed and PC board should pay attention to when carrying board face, damage to the edge. With scissors or boring things according to the required standard after the trade-offs, peel off along each side of about 50 mm again after coating equipment, other equipment completed until after the tear. Also need the attention, all opened the seal the edge should be of the appropriate film to prevent water, dust, or other intrusion.
b. 在后面章節中，中空板的最小彎曲半徑是其厚度的175倍，只可以冷彎，不能熱彎。
B. in a later chapter, hollow plate the smallest bending radius is 175 times of its thickness, can only cold bending, hot bending.
c. 實心板的最小彎曲半徑是其厚度的150倍，6mm以下厚度可以冷彎和熱彎成型，8mm以上的厚度則需要熱彎。
C. the smallest bending radius of solid sheet is 150 times of its thickness, under 6 mm thickness can be cold bending and hot bending forming, hot bending is required to the thickness of more than 8 mm.
d. PC板應順骨架方向設備，使水滴下滑。板頂邊運用防滲防塵鋁箔帶密封。板底邊用特制有孔透水式鋁箔帶封底可使冷凝水流走。
D. PC board should be along the direction of skeleton equipment, make water droplets fall. Top edge of plate using anti-seepage dustproof aluminum foil seal. Plate with a hole bottom edge with special waterproof type of aluminum foil with back cover can make the condensed water outflow.


e. 有必要為PC板材的熱膨脹預留空間，每1000mm長的板材約預留3mm，并確保滿意槽深。鉆孔直徑應大于螺絲直徑的1.5倍。
E. it is necessary for the thermal expansion of the PC board room, around the reserved 3 mm, per 1000 mm long plank and ensure satisfaction groove depth. The hole diameter should be greater than 1.5 times the diameter of the screw.
f. 密封系統分為干式系統（運用EPDM或其它相容性膠條）和濕式系統（運用認可的中性硅酮密封膠）兩種，不可以用PVC材料進行密封。
F. sealing system is divided into dry type system (use EPDM or other compatible strip) and wet system (using the neutral silicone sealant) approved by the two kinds of, can't use PVC material for sealing.
