You should read this again.

It is important to clarify the reason why OFHC copper is used in place of pure, unalloyed copper. Unalloyed copper is an important metal for cables because of its high electrical conductivity. Electrolytic tough-pitch (ETP) copper is an inexpensive industrial copper used for the producing wire, rods and strips. ETP copper has a nominal oxygen content of about 0.04%. Oxygen is almost insoluble in ETP copper and forms interdendritic Cu20 when the copper is cast. For most applications the oxygen in ETP copper is an insignificant impurity. However, when ETP copper is heated to a temperature above around 400C / 752F (such as when using a high temperature solder) in an atmosphere containing hydrogen (found in air), the hydrogen can diffuse into the copper and react with the internally dispersed Cu20 to form steam according to the chemical reaction:

Cu20 + H2 (dissolved in Cu) --- 2Cu + H20 (steam)

The large water molecules formed by the reaction do not diffuse readily and therefore form internal holes, particularly at the grain boundaries, which makes the copper brittle. Brittle copper at solder joints (the area that has been heated) will decrease the life of the cable since this area is usually under high stress from supporting the weight of the cable at the connector point. To avoid hydrogen embrittlement caused by Cu20, the oxygen can be reacted with phosphorus to form phosphorus pentoxide (P205), but this is not practical when hand soldering RCA connectors onto a coaxial cable. Another way to avoid hydrogen embrittlement is to eliminate the oxygen from the copper by casting the ETP copper under a controlled non-oxygen reducing atmosphere. The copper produced by this method is called oxygen-free high-conductivity (OFHC) copper and is alloy C10200. OFHC can be heated and soldered in an open environment without becoming brittle at the heat effect zone (solder joint).

I'll dumb it down for you again. It says that ETP when heated becomes brittle, but there is a process that will turn ETP into OFHC, which is not brittle when heated. What it does not say and neither Belden or BJC say is that they use that process to make their cable into OFHC. A point sorely missed by you...again and again and again.

Furthermore, BJC admits that the use ETP, not OFHC.

Anyway, thanks for posting that as it supports my position......LOL

It doesn't support your position. Because they are talking about hand termination, via soldering, of RCA cables.

There are other termination methods out there.

Nice try. You are welcome to the batters box as much as you care to at this rate. Too easy.

I like how you gloss over the BJC post in it's entirety. A quick search of various sites should also speak to the reliability of their product.

Again what can you actually show us that makes ETP a problem for HDMI cables?

I understand your vacillation on answering even the most simple of questions. That's ok, keep dancing.

I have a 33 foot PE cable running a conference room projector for 4-5 years now. 1080P and no issues. It's most likely ETP also

It cost something like $28. It's only been unplugged once at the PJ side for a bulb change.

You're the one that used that article to support your position in the first place and now that I have proven that it supports mine you want to try to twist it around......LOL. The fact is they are talking about any ETP wire that is subjected to heat whether it be an RCA or whatever. I'd say nice try, but the reality is it's yet another huge FAIL on your behalf. :rolleyes:

There's nothing to gloss over. I stated a fact that Belden/BJC uses Electrolytic Tough Pitch copper, with a purity of 99.95 percent. Nothing was altered, it's direct from their site. The one link I provided is actually to the BJC site, although it is a Belden pdf. The man wanted to know what bonded cable was, I provided him with that answer. Talk about making mountains out of mole hills. :rolleyes:

Again what can you actually show us that makes ETP a problem for HDMI cables?

You already did that, thanks!

It cost something like $28.

Bravo, you truly are the champ of the cheap. Send me your addy and I'll send you a crown made from inferior ETP. Disclaimer: I'm not responsible for broken/damaged terminations.

You are either delusional or in denial. The argument you are making is that ETP is going to make for an unreliable HDMI connector, correct? I have yet to see a single shred of empirical data from you in that regard. Which with you is a given.

You do realize that all your CATV, Data, Telco is all ETP and compression terminated or soldered right? Are the traces on any PCB assemblies your gear has OHFC?

Care to back it up?

The article talks explicitly about ETP + RCA Connectors + solder terminated by hand. It is speaking to a specific subset where there can be a brittle connection.

We are talking about HDMI and most likely COMPRESSION termination.

Remember I didn't bring up ETPC as it is concerned with HDMI. I did bring it up as concerned with RCA connections that are terminated in a certain manner. The fact you don't see this speaks volumes.

I work at a small regional hospital. Three of us ran 63,000 foot of CAT6, RG59, Multi-mode fiber etc... This resulted in 1500 terminations of ETP based CAT6/RG59 alone. All compression based. Nary a soldering iron to be found.

All our CAT6 passes certification (we brought in a vendor to certify). Out of all these runs 0 had to be re-pulled and we had to re-terminate 27 because they were borderline but in the margin.

Wrong again, sport.

Brittle copper at solder joints (the area that has been heated) will decrease the life of the cable since this area is usually under high stress from supporting the weight of the cable at the connector point.

That applies to any cable, they use the RCA as an example. As poor as your reading comprehension is, I'm surprised you graduated HS.

He doesn't have to, you do that every time you post.

How are HDMI cables terminated sport?

You started to make a stink about ETP HDMI cables and now you can't get your pants pulled up quick enough when I posted an article about when ETP can become a potential problem. First rule when you find yourself in a hole is to stop digging.

I have cut into several HDMI cables cheep ones and they were all soldered. None used crimped fittings. Can you link the tool used for making cables with those types of fittings?

Most assemblies are compression terminated. Just hit youtube and search for HDMI termination. Most facilities use a mechanized version of this.

Phasewolf

The several I have sliced apart because they had failed were all soldered. Just saying what I have seen.

There are certainly junk HDMI's cables out there. I simply recommended a Blue Jeans HDMI cable that starts at $20. BJC makes good product and it's built properly.

Greenlee, Liberty, Covid, even AQ make termination kits.

If we get lucky HDMI will die a painful, agonizing death. To be replaced by standard Ethernet Cabling.

328 foot runs, Power over Ethernet, etc....

You're the one that brought up the cable/heat problem with your quoted article, chump. Proof positive that you had no idea how they were terminated.

You started to make a stink about ETP HDMI cables and now you can't get your pants pulled up quick enough when I posted an article about when ETP can become a potential problem.

If that made any sense I would address it.

You should heed your own words as the dirt has already buried you in the hole.



I really wonder what you're doing here. I mean, all you do is troll threads, no one ever agrees with anything you say, you contribute nothing positive, you drink a lot of Kool-Aid, you haven't made a single friend and worst of all, you are consistently wrong. Way past time for you to move on.

ouch...that's gonna turn into a shiner come morning.
