Preliminary speciﬁcation

Desktop video & FM radio module

system CCIR I

FM1246

Aerial connections

Standard-phono socket female 75

Ω or IEC (female for TV,

male for FM radio).

Solderability

The solderability of pins and mounting tags when tested

initially and after 16 hours steam ageing in accordance

with

‘‘IEC 68-2-20’’, test Ta, method 1 (solder bath

235

±5 °C for 2 ±5 s), results in a wetted area of 95%.

No de-wetting will occur when soldered at

260

±5 ° C for 5 ±0.5 s.

Resistance to soldering heat

The product will not be damaged when tested in

accordance with

‘‘IEC 68-2-20’’, test Tb, method 1A

(solder bath 260

±5 °C for 5 ±1 s).

Mass

Approximately 50 g.

Robustness of pins

The pins will not be damaged when tested in accordance

with

‘‘IEC 68-2-21’’ :

• Test Ua1, tensile of 20 N in axial direction

• Test Ua2, thrust of 4 N in axial direction

• Test Ua2, thrust of 2 N in axial direction.

Punching pattern of chassis PCB

Field rejects are often related to broken tag joints.

Therefore, the following punching pattern is recommended

(see Fig.6).
