Replacement for the PM9610 Prescaler for Philips PM6654 High precision Counter

<< < (14/18) > >>

SaabFAN:
Small update here to Rev. B (which I'm actually going to order):
- Coplanar Waveguide Vias now 0.5mm hole and placed in a denser pattern.
- Added a 0 Ohm resistor as a jumper in the +5V rail
- Replaced D4 and D7 with 1N4148 (before LL4148)

The addition of the jumper link and replacing the 2 SMD Diodes with Through hole basically adds a "3rd Layer" to have a completely uninterrupted GND-Plane underneath the RF-Traces (before the divided signal had to cross these 3 signals) :)

SaabFAN:
Well, new boards are ready to order, but I since I discovered the opportunity to buy them ASSEMBLED from JLCPCB, I'm considering to do just that :)

Does anyone have any experience about buying them assembled from them? The Previewer sometimes shows (especially on larger chips) the chips to be in the wrong orientation. Wouldn't really make sense to have them assembled and then have to redo all the chips if they're in the wrong orientation.

geostep:
SaabFAN,

Is it possible to ask them to run a test batch of one to see if all components are oriented correctly?
Perhaps with the understanding that you won't pay for their errors?

SaabFAN:
I went ahead and asked JLCPCB after making sure that my files are correct and they replied with the statement that their previewer has a bug and they have an engineer checking the rotation and correcting it if necessary.

BUT The parts I want to use aren't in their parts-catalogue and similar parts are "extended parts", which cost 3€ each to change the reels. So the boards will only be partially assembled (only 0603 and 0805 Capacitors and Resistors will be on the board) with "Some Assembly Required" :)

geostep:
I can't wait to see what the partially assembled boards will look like when you get them!

- George
