I’m so glad people still repair these classic machines, they are part of our history and bring back many great memories. Nothing better than being a kid with a pocketful of quarters a mouthful of bubblegum and not a worry in the world. I’d go back in a second

@Paddington2000 3 года назад

So, it's not that the lead and the tin separate out from the solder alloy to form a cold solder joint, it's when insufficient heat is applied to the component and pad that the solder doesn't flow properly and or, the joint has been disturber before it has had time to solidify properly making the solder on the joint crystalline (matt grey in appearance) and therefore brittle which also has a higher resistance, this can cause the joint to run warm, the continuous heat/cool cycling causes thermal stress which leads to work hardening of the joint followed by a fracture and premature failure. The problem with the header pins failing is just stress and fatigue through many mate/un-mate cycles of the connector causing the joint to work harden and fracture or crack prematurely.

@LyonsArcade 3 года назад

@danieltiemeyer3234 3 года назад

O.o had a Williams Road Kings that the G I would go dark. Tap the relay on power supply, G I is back. Then quits. I pull power supply and all solder looks good. I put back in. Problem continues. I pull power supply again, and was a cold solder that looked fine. Resoldered and never saw that problem again.

@LyonsArcade 3 года назад

Yeah I honestly think sometimes the chemical components or minerals are separated in the solder enough that it won't conduct electricity but looks fine...

re: cold solder - Yes solder is a combination of materials that all melt at different temperatures. A cold solder joint is when not enough heat is used to heat all parts of the solder, and the component to be soldered and circuit board pad. Over time the flow of electricity will rob electrons from solder, weakening the solder joint, causing cracks over time. as connectors are pulled off this causes old solder joints to crack. On ships zinc anodes are used to prevent the robbing of electrons from ships metal hulls. The zinc being the weakest material is the one that looses the electrons. It is precipitation static (the ship physically moving through the air/water that causes that creates the static electrical movement) that creates the electrical flow through the structure.

@LyonsArcade 3 года назад

The 'robbing electrons' thing is what I kind of suspected happens but I didn't know what to call it :) Crazy how there's more going on than meets the eye...

@xenodaemon 3 года назад

Be aware that with less voltage applied to the displays, they will draw a little more current. Might be an issue with a fuse or resistor, but hopefully, it will be within allowances.

@Sunsetdrivein 3 года назад

On those score displays, any time I find any of the R1, R3, R5, R7, R9, R11, R13 bad and they are originals, I replace all of them with half watters. This prevents a "callback" service call on the displays.

@LyonsArcade 3 года назад

Definitely a good idea!

@petermichaelgreen 3 года назад

BTW you can get 0.6W metal film resistors that are the same size as 1/4 carbon films. Might make for a neater job.

@waynegram8907 3 года назад

JOES CLASSIC, why does the voltage rise higher when the power supply components are going bad, what is causing that issue? The displays should have 220VAC or 220VDC at all times because the factor connectors on the PCB get burned up because the voltage is at 220vdc which the PCB connectors and display connectors aren't rated for voltage at 220VDC?

@PlumGurly 2 года назад

Yeah, cold solder joints can have multiple causes. Usually, that is due to sloppy soldering, but yeah, physical stress can cause a similar phenomenon. A reemerging problem is "solder whiskers." With time, certain materials will "grow" protrusions. Adding lead to solder helped prevent that somehow (scientists don't really know what causes this, though physical and electrical stresses seem to contribute). Well, with ROHS laws in EU countries, lead solder is being phased out. So whiskers are starting to return. The problem with those is when they create solder bridges over time. And yeah, Radio Shack batteries are rather old, they admittedly, Radio Shack had good batteries. Around Christmas was always great for their batteries, and some even seemed a tad over the voltage. So my guess was that they were just made, so there was no shelf wear at all. I mean, flashlights seemed to be brighter, toy cars a little faster, etc.

@keithcitizen4855 3 года назад

Talking about cold solder joints, I dropped my tv remote control and it was enough to break the connection at the led on visual inspection it looked like plenty of solder used and nothing wrong but it it seems the PCB was heat insulated by flux during soldering, can just imagine the factory pushing their workers to fulfill quotas.

@russellhltn1396 3 года назад

A cold solder joint is a defect in soldering. It's either a manufacturing error or a bad repair. What you're talking about is cracked solder joints. Those happen from mechanical stress or thermal cycling.

@ChucksBasix 3 года назад

Not exactly what a cold solder joint means... It's usually a weak joint formed when you don't get the components hot enough for the solder to freely flow, and properly attach to both components, thus causing resistance, among other things to happen, and eventually failure of the joint.

@LyonsArcade 3 года назад

@EsotericArctos 3 года назад

Sprague are really good capacitors. I would probably still do a series leakage check and ESR check on the capacitor, but more than likely if the voltage and ripple is good on the 5V line, definitely leave it in place. Those Radio Shack batteries would be pretty ancient by now..... Your description of a "cold joint" is pretty good. The name came from joints that sometimes were soldered with too cool a temperature or that were cooled too quickly, but is generally also used for "cracked" joints as from age as well. A dry joint is termed because it is made without enough flux, so it is "dry" soldered.

@LyonsArcade 3 года назад

Thanks Brendan I didn't think about it not being heated enough, that's interesting and explains the terminology!

@Shamino0 3 года назад

Hi, Ron. I've got a quick question for you. Lots of pinball machines have what appears to be a white light on the front apron, on the left side, above where the instructions card goes. What is that light supposed to be for? I've never once seen it turn on on any pinball machine I've played over the past 40 years.

@LyonsArcade 3 года назад

That is a great question. That light is called "The Credit Light"... there was a time when in some areas, pinball machines were illegal because you could win free games on them. Because you could win free games, it was considered a gambling machine in some areas... so the laws were different all over, but in some places it was LEGAL, if you didn't tell people how many credits they had! So the pinball companies tried to make 'work arounds' for that, and one of the things they did was add the credit light on the apron. If the game has a credit on it, that light will light up, but in those particular locations it will not tell you on the backglass how many credits you have, the light just stays on until you run out. The 'logic' behind this was that if you won 5 free games, you could sell them to somebody for a dollar instead of the 1.25 they'd pay to play them, hence you were using the machine to win free money. It's completely crazy but it comes from another time and we have plenty of craziness around now too I guess so I can't really criticize it too much. If you've never seen one on it may be that it only works if the credit display is turned off on the game (there's a dipswitch to turn the credit display off). I'll try to mention it in a video in the future and see if I can get it to turn on.
