The solder material (japanese) recommended from UVA is no longer available. Chris ordered similar materialial from other company to exercise. Working on the sole source procurement of the ASICs. Fermilab is also intersted in the same ASICs and Fernando discussed if we can share with Fermilab the costs | - Fernando: the first article signal cables will arrive by mid November and Chris is working on a board to be used for testing.
