AN OPTICAL SUB-ASSEMBLY FOR A TRANSCEIVER |
摘要 |
An electro-optical device (1) has a lead frame (3) having a through-hole (10) acting as a locating feature for a mould pin for moulding a body (4) incorporating a lens (5). The hole (10) is also used as a reference for a placement machine placing a component (2) within 1.5 mm of it. Subsequently, after withdrawal of the mould pin a recess (35) remains, which can act as a locating feature for a waveguide termination connecting to the device. Also, the device comprises a ground plane (55) bonded to the back of the moulded body (53) or (72) incorporated in the lead frame. |
