I just went through our orders for capacitors and have found out, that we have changed almost 300 pcs of them. They were all kinds of 411s, 750, 450, you name it. We've also got some of the older 600 routers; all of them were puffed up.
I think it's a real pity that Mikrotik behaves so unresponsively. They should have let us know about the problem and help us out. Instead they have denied everything even when we alerted them and asked them to help us. They should have identified shipments with the problem and at least send the capacitors and instructions. Fair deal in my opinion would be a 50€ credit for each and every crippled shipped unit. This is how serious companies like Aruba Networks or Ruckus would take care for those who actually makes their money at the frontiers with the end users.
We’ve lost more money on the repairs, replacements and travel costs than we have earned from the sales in two years, just because of these stupid capacitors.
As you can see, good Panasonic capacitor costs 0,113€ if you buy 1000+ http://si.farnell.com/jsp/search/produc ... ku=9691847
. I do not know the Mikrotik supply chain logic, but it must be a pretty cool one.
For soldering, we are using weller 80W station, I think we go with 440°C. It works quite well after you change 50 or so capacitors…
