I've only just started watching and I'm already getting flashbacks to my time working in a factory making boards for PCs and PS/2 systems. I mostly did testing of the final product, but I also got to apply engineering mods to certain runs of boards. In our case we used hot air blowers, both stationary and hand-held. Interestingly, the hand-held unit I remember looking a lot like a standard hair dryer, which is kinda scary, as someone could conceivably prank someone with one of those. Only it would probably burn a hole in your head before you realized what it was. As for the technique used by the factory I worked in, I do recall having to be very careful about not keeping the PCB under the hot air for more than a couple of seconds.

@Epictronics1 2 месяца назад

Cool job :) Yeah, hot air and solder paste is a great method too. On these few SMD components, I'm not sure it matters much but on larger projects, it's a better method for sure

@g4z-kb7ct 2 месяца назад

14:26 Pro tip: To keep it looking clean you should have plugged the JTAG cables into the connector but not soldered it in. Then hold the connector in place by pushing sideways and applying some pressure then program it. It usually only takes a few seconds to program a chip so you will only have to hold it for that amount of time. Obviously it must be held by pushing sideways at an angle so the pins contact so get the software ready, hold the connector and then click 'program' while holding it firmly. After it's programmed you just lift off the connector and it looks clean and those holes also stay clean. Something to remember for any future JTAG programming :-)

when drilling hardend metal, use machine oil OR water as you drill to reduce heat, drill a small pilot hole first then step up to a larger drill bit as you are removing less metal and less heat each enlargement. Also get a cheap tool called a NIBBLER. good for cutting straight edges on sheet metal even square holes to size

@Epictronics1 2 месяца назад

A nibbler would be awesome to have. I drilled in three steps but it still got too hot. I should have used oil for sure

@g4z-kb7ct 2 месяца назад

@@Epictronics1 Oil is really messy, don't do that. He means 'machine oil'. It's water-soluable oil (coolant) that is white when mixed with water in about 10:1 ratio and is used when machining parts in engineering workshops etc. As a retired 1st Class Machinist / CNC Programmer for 30 years we used that stuff everywhere in all our machine tools. For jobs at home where you know it's going to get hot, put a block of wood in a plastic tub (do it outside) and fill with water to just submerge the wood then put the part on top of the wood and drill it while under the water. Edit: Anyway you can fix it. Just use some 600-grit wet&dry sandpaper and polish it and it will look like new.

@Thelemorf 2 месяца назад

Its not rly hardened material, the back plates are made of some type of stainless steel. That means when drilling you need to have extremely low speed but high pressure, and use coolant, to be successful when using HSS bits. Otherwise just go with cobolt bits, but May be overkill for that one time use..

@g4z-kb7ct 2 месяца назад

21:52 The minimum PCB order is usually 5 pcs so what I usually do with my nice projects is use one of the spare boards and build another one complete then put it on my display shelf. If you do that be sure to solder all the parts into the board without sockets because rarely are parts in sockets on production boards. You have the skills to remove any parts and replace but since it's only a display piece that won't need to be done. Soldering everything in will make it look even nicer.

A good method for small smd components is to tin one pad, then put the part together with the soldering iron in this pad and position it. Afterwards, solder the other pad. Works fine, even without flux. I'm using flux only for components with multiple pins and/or hot air. What also works good is solder paste. Just a bit on every pad, put the parts into it and let the hor air do the rest. Gives great looking solderjoints and looks just like factory.

@Epictronics1 2 месяца назад

Yeah, I need to remember to get some solder paste. Thanks for the reminder 👍

@g4z-kb7ct 2 месяца назад

@@Epictronics1 Solder paste is really just tiny balls of solder and flux together. You really don't need it but if you are going to use it then use it as intended.... apply paste, put the parts in place and hot air it without touching it. Paste is most useful for a reflow oven where parts can't be mounted manually. For home projects it's not required especially since your manual soldering skills are excellent.

You have plenty of random old PCs there so to save all the messing around it's better to use a real PC running the required OS. When I program my CPLDs I use an old laptop running Windows 7. Yes that Xilinx software is a real dog... 1GB of junk to program a CPLD lol edit p.s. You might be able to replace the NJM3403 with a LM324. The NJM is specifcally made for audio applications but the LM324 is pin compatible and should work. If you are able to swap out the NJM for a LM324 and compare the audio I would be very interested to know if there's any audible difference :-) edit p.p.s. You can solve the long cap issue by first bending the legs at 90 degrees before soldering so it sits flat against the board.

If the drill is getting hot you're probably running it too fast: when drilling steel the drill should be run at a low speed with a lot of force -- 20kg of weight on the drill or more would not be unusual for a wide bit like that! A drill press for metalwork will give like 4x or 10x mechanical advantage and generally run slow for exactly this reason. Drilling steel with a handheld drill is super miserable, but it's possible if you really lean into it. Getting a clean hole is another matter.. Once you've overheated the bit, it loses temper, and will get dull really fast.

@Epictronics1 2 месяца назад

My drill press only takes small drill bits. I hope to get a much larger one someday. I was pretty lucky to get this good result handheld

@g4z-kb7ct 2 месяца назад

@@Epictronics1 You don't need to guess the speed. There is a formula... RPM = cutting speed (m/min) x 1000 divided by (Pi x drill-diameter). So for a 10mm high-speed-steel drill with standard cutting speed for steel at 30m/min, 30 x 1000 / (10 x 3.14159). RPM = 955. If the steel is hard reduce the cutting speed to a smaller number and recalculate (15 is a good start for hard steel). I'm sure there is an online calculator somewhere. Cutting speeds for various metals and other materials are available online. As a cnc machinst I usually started with a cutting speed of about 300 - 400 but that was for carbide tools :-) I have a vid of one of my machines drilling a 60mm hole at 1000RPM using a carbide indexable tip drill (we call them U-Drills) in 4140 steel.

@g4z-kb7ct 2 месяца назад

@@Epictronics1 Like most technology it's a remnant of past times. It's easier to poke a resistor into a hole manually if the legs are longer. It also allows variation of hole spacing. If the resistor was pre-made to fit a 0.400" hole spacing (common for 1/4W resistors) and some board had wider leg spacing the resistor would not fit. Also, if you keep those resistor legs you can re-use them to patch a trace, make a jumper or build up a circuit on a vero board :-)
