Question: Maybe someone has experience in this field.

I'd like to overmold a PCBA, which has SMT components, with a low pressure molding process.
I am concerned about the temperature of the hotmelt material when it reaches the PCBA. The temperature should be between 200°C and 215°C.

Does anyone know if this material temperature could be a problem for the electronic components? Do I have the risk that the solder melts? Is this stress too harmful for the components?

I am not quite sure if the components will be able to withstand this temperature or if I should take as a reference the reflow temperatures of the components.

Answer: 
Make the two input resistors significantly bigger (say 10xR) - the gain will now be lower but you can added an extra amplifier onto Vout to restore the gain you need. Be aware of common mode problems with this type of circuit - you'll probably need to use 0.1% (or better) resistors to get an accurate representation of your 1-5V signal.
unlike Andy's answear i wouldn't use input resistors on your input. they add [noise](http://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise) to your signal. of course its depending on your application.

what i would use is something like an [AD8479](http://www.analog.com/static/imported-files/data_sheets/AD8479.PDF) which is exactly what i think you want. high input offset voltage is the keyword here
