Quality capacitors: Nichicon

Note to self: I was watching EEVblog #378 – Dumpster Diving Teardown Repair and EEVblog #763 – Dumpster Plasma TV Bad Cap Repair and Dave Jones says Nichicon make high quality capacitors. Apparently Panasonic, Nippon Chemi-Con, Rubycon, and Cornell Dubilier are also good.

Soldering tips from Dave Jones

In his video EEVblog #186 – Soldering Tutorial Part 3 – Surface Mount Dave Jones says to use soldering iron temperature of 300°C to 350°C. He set his hot air gun at 350°C.

He also recommends 4x or 6x magnifications for 0402 SMD and recommends not to use them (or smaller) unless you have to because they can increase manufacturing costs due to being small and fiddly and requiring magnification during soldering. The smaller components can affect yield.

For solder he recommends 0.46mm solder (recommended Multicore brand). And flux. Always use flux.

Also he’s on the record as preferring a chisel tip. In this video he also demoed a thing called a “well tip“, which I have never seen or used before. Apparently good for drag soldering?

While I was researching this post I came across the Hakko Product Lineup, they have some nice looking kit!

p.s. in EEVblog #180 – Soldering Tutorial Part 1 – Tools Dave suggests solder in this order:

  1. 62sn/36pb/2ag
  2. 63sn/37pb
  3. 60sn/40pb

The first one with silver in it can be good for some SMT devices. The second one has a more stable melting point. The third is tried and tested but has variable range of melting points.

Note: sn = tin; pb = lead; ag = silver.

Gah!

I am way behind on my videos for In The Lab With Jay Jay, but it’s not for lack of trying! I’ve recorded the video for project 9 of the Maxitronix 20in1 something like five times now, but I still can’t release it because the circuit will not work as advertised. It’s suppose to be a demo of a monostable multivibrator, which is also known as a one-shot multivibrator, but the circuit isn’t working the way that a monostable multivibrator is supposed to work. I’m still in the process of debugging it. I think the problem is a problem with instructions and not my implementation (the instructions are fairly low quality and unreliable in my experience so far), but I haven’t arrived at the bottom of this one yet. I will continue to try and solve this conundrum tomorrow.

Triple 4k monitors

Well, shit kinda got out of hand, and now I have three 4k monitors on my desk.

I didn’t intend for this to happen. What happened was I thought that one of the monitors that I use for my computers on the bench and in the booth was broken. So I hastily ordered a replacement. Then it turned out that that monitor wasn’t broken — the power cord had fallen out — but by the time I had discovered that eBay was telling me it was too late to cancel my order.

So for a lousy AU$250 I now have a third monitor attached to my primary workstation. Since I have pretty much no need or use for a third monitor what I have done is create a desktop background image for it with a bunch of reference material.
