250g-500g 1/0.5mm Lötzinn Lötdraht Löt mit Flussmittel Lötkolben Lötstation DHL (WHL #68F1)

(Follow-up post to the solder test of WHL #68)
While we’re at it – I couldn’t resist testing the flux percentage. Which also resulted in having large samples for a visual comparison. Contrary to my expectations, the lead-free solder wasn’t the one that stood out…

First things first. New batch, same naming scheme as before. Since I already measured weight per meter, I just picked one sample length from a (new) lead-free U1.0 wire and cut the others to expected length. 100cm of that stuff is 5.42(196)g, for comparison. […]

250g-500g 1/0.5mm Lötzinn Lötdraht Löt mit Flussmittel Lötkolben Lötstation DHL (WHL #68)

A beefy electronic load (#P4F1)

Well, that was a long week…actually, it was a fortnight ;)

Here we go!

So this puppy was manufactured by my new friends over at OSH Park (ordinary order, no extras) and I think I hit the express jackpot. I registered on June 8th and submitted my files – three hours later (1 AM my time on Friday) I already got notice of the panel assignment. Maybe the small size of 54mm x 31mm (2.1″ by 1.2″ for the Yankees out there) just made a perfect fit on the remaining board size and they sent it straight to production ;) As OSH Park charges 5 dollars per square inch of board area (for three units!), […]
