Desktop video & FM radio module
system CCIR I
Preliminary specification
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).
