| 摘要 |
A planar circuit housing (300) for containing a planar circuit (120) is disclosed. The planar circuit housing (300) comprises a support portion (341) for supporting edges of the planar circuit (120), the support portion (341) being provided on at least one housing internal surface substantially perpendicular to the planar circuit substrate (120); an upper cavity (380) in the housing (300) above the planar circuit (120); and a lower cavity (382) in the housing (300) below the planar circuit (120), the lower cavity (382) having the same sizes as the upper cavity (380) in directions parallel with the planar circuit substrate (120). |
