The progress is too slow, the frequency sweep instrument PCB

is actually painted the most tangled piece of PCB, the left wiring is very easy, but the right 32 chip to FSMC, there are a lot of out of the IO port, cross-tangled together, there are a few lines all the way to hit 3, 4 through the hole, it is difficult to cloth.

Engineering Check the next is the June 17 painting schematic diagram, today, at noon, and then today 3 o'clock in the afternoon to vote for Gali, almost two weeks of time, although there are several examinations in the middle of the delay, but also the progress is too slow, never allow!

This attempt by the top-down schematic design, itself is to make the project clearer, but the final painting directly in the PCB to add components to modify the network cabling, have to say that the speed will be fast, for time too late design, so should be better.

The board is expected to reach the July 6, the middle of this period of time to do lock-in amplifier, first determine a plan, and then see July 10, three days can do it.
