My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

Well, that's not very fair, is it? Did you not read post #53 and #56? That's all there is to it. Like you say, soldering is not rocket science, but needs some practice. He was given a google link but I did not pick any specific video, I think he should do that selection on his own.

You are correct, I owe you and anyone I have offended an apology, I did read post #53 but I unintentionally skipped over the paragraph that starts with "...remove every large clump" as I was more attracted to the do's and don'ts picture. I also totally missed post #56 entirely.

I'm very sorry to you and anyone else I offended, at the time I felt it was a fair comment to make however I was wrong so I'm sorry about.

Anyway, while it may have a nostalgic value for you, I personally would only keep it as a memory.

I understand.

Regarding flux, I stand by what I have said. It is waste of money. On electronics one should not use any other type of soldering wire than the one with flux in the core of the wire. As a matter of fact, too much flux can also cause problems, so it is not true that using flux can not hurt. Flux fluid is used only in industrial soldering, where the PCB is travelling through a flux foam first and then through the melted soldering wave.

Ok well now you've got your wires crossed because flux is not a waste of money at all, it helps and there is no questioning that. It is used extensively in the repair/rework arena by many and my own real life experience is that it does help with non SMD soldering too, especially when you're dealing with old pcb's. If you've got it handy there is no reason not to use it in my opinion and that is how I solder.

I stand by what I said and think it will help Ravi along with his soldering.

Manual soldering of electronics don't need any flux foam or liquid.

My experience is that if there are balls then it is enough to heat them well up, until completely melted and either suck it up or in many case it will float out because there is normally enough flux around the points. If if does not float out and look like figure A in the picture I provided then there is nothing else to do than suck it out and apply new solder.

No one said it did, however they put it in the solder core for a reason. Exactly, in your experience...

Camera, I'm just offering Ravi what I can from my own understanding and experience, earned from actually doing it and experimenting myself. I do not proclaim to be some kind of authority on soldering.

My second post with the video was somewhat meant in jest, I thought that would be apparent when I said "the astute of you will identify", sorry if that post offended you or prompted you to feel the need to explain your own authority/experience, again that wasn't my intention at all, it was just a light hearted joke that also covered the "why use flux" for anyone who wanted it.

Here is a link to Louis Rossmann's YouTube channel, he is one of many that use flux every day, day in day out to get their work done.

His video's will demonstrate what I am trying to explain regarding using flux or not and will have the last word on my behalf, you the reader can decided if or not you would like to try some additional flux in your soldering diet.

Lee you have not read this post from the beginning I feel. The questions you have asked have all been answered.

Ok thanks I will have another look, will probably leave adding anything else so Ravi can get his build log back on track.

Thanks and sorry to all
