[SI-LIST] Re: Press fit connectors

Suvedha,

Am using conectors  although not press fit

Some considerations

1. There is an impedance mismatch  if using this connector. Please check with 
the vendor for  char impedance
2. Check if there are any predefined layout rules for this connector so that 
char imped is achieved ( eg a T structure)
3.How many insertion cycles the connector can sustain?  Will be specifed in the 
datasheet. Most RF conectors do not stand more than 25 cycles. Run into 
reliability  problems, long term

Regards
Bharathi
