C'mon people 54 caps is not that much:)

try to solder a russian zx spectrum clone with 70 smd capacitors lol

67 + 7 caps isn’t much... for a single board build.

But try doing that 50 times!

OK. 5 Pieces of 1260r1 have been ordered with partial assembly and some better PCB options than the previous order.

Sending 2 to @ChuckyGang, 1 to @Supaduper and 1 to @AlenPPC.

Keeping one myself obviously. I am going to personally use a -5 Xilinx part for the RAM CPLD this time.

Just out of interest, At a glance If you go to 'Tools' Menu -> Statistics -> "Element" Tab in Eagle what does the breakdown of caps on the top vs bottom layer look like from the frame on the bottom LHS? Might be necessary to generate the report file to total them up more easily.

There are 67 100nF caps and 7 1uF caps on the bottom of the board. JLC have selected X7R parts for the assembly. I cost $7 to get the the assembly done which is absolutely worth it to save a few hours of soldering. My time is definitely worth more than $1 an hour.

EDIT: actually it’s a -6 CPLD. 32 quid plus vat per chip :/

Agreed, there are far better things to be doing in life than hand soldering SMD caps on an industrial scale. I'll await the live stream microscope inspection reviewing the quality of the JLCPCB placement + soldering finish :)

Software controlled fan! Nice.
So glad that TF 060 options will be a reality in 2020.

i think no costs so much more to add active parts for one board if you add the cost of the parts plus shipping .but 32 euros one single ic ouch i think when i go to build one i will buy with at least capacitors plys cpld presoldered.

The CPLD part i'm using here is like x2 the required to make the board work.
