  • Not really. The correct way to dispose of asbestos is literally to put it in a garbage bag and send it to the dump. As far as a hazardous material it’s only really bad for people. It’s almost entirely chemically inert so it’s actually far less bad for the environment than most of the stuff that winds up in the dump. Even ocasional exposure wont do anything to most people (not that it’s good for you of course). It’s mainly an issue if you work in an industry where you handle it every day.

    I had to do some asbestos remediation in my house a while back (removing plaster filled with it) and I contacted the county about proper disposal. They literally just told me to bag it and huck it in a dumpster.


  • I’m not saying we played fast and loose with the spec. I’m saying that there are plenty of places where the actual spec doesn’t use numbers and it is a judgement call for example minimum lead protrusion.

    There are also plenty of places where a number is given but it is not possible to measure such as barrel fill on through hole components. In those situations an inspectors best bet is to eyeball it and if it’s even questionable to rework and correct the process so it isn’t. You don’t eyeball it when it’s close, but you also don’t need to measure, for example, lead protrusion on every lead when they all apear to be definitely under 1.5mm.




  • Your recorded voice actually sounds really similar to mine and I think it sounds fine. I think the main issue is probably just that you could have a better mic setup. A good sound setup makes a world of difference over even a decent one. Like I said, your voice isn’t bad at all but there’s a reason pros spend all sorts of money on expensive setups.

    If your voice is something you’re uncomfortable with you can also train it on your own. Even people with naturally amazing voices often do vocal exercises of some sort.


  • Once again this is a question of tolerance. It could be a place you only care about minimum clearance. If the spec is for a gap of at least 15 mil then a pack of 30 mil key cards makes for a bunch of cheap easily replacable go/nogo gauges with enough leway that even a worn one won’t put you under spec.

    I’m most familiar with IPC standards for electronics but even in the most critical class 3 applications there are plenty of spots where the standards are effectively gauged by eyeball let alone with even a makeshift tool because those specific specs aren’t that critical for the application.


  • I can’t know for certain what is specifically going on there but I do work in contract manufacturing for high end scientific equipment and critical medical electronics so I do know a fair bit about the processes used. For me the dishsoap and keycards on their own don’t raise any alarms. It sounds like the main issue is poorly written incomplete manufacturing instructions, which is a big enough issue on it’s own and is an absolute monster to try and fix once your production workers have gotten used to working like that.

    the soap should either be specified by brand in the manual or swapped to a certified lubecricant, that has been tested to work fully with the gasket and not cause deteriation or on any way affect the quallity of the seal.

    1. The seals used are most likely silicone (it’s what we use on environmental chamber doors). If so there are very few chemicals that will harm them let alone dishsoap. We actually use 409 (a bathroom cleaner) spray to lubricate our seals where I work.

    2. The dishsoap is almost certainly something they order and stock with their own internal shop supply number. The instructions most likely reference that number but that number would be meaningless to anyone else so the news article just said dawn dishsoap. It’s not going to be any random dishsoap because that’s not how industrial supply works. It would be more expensive for them to go pick up random dishsoap than to just keep ordering the same part number (that specific dawn dishsoap) in bulk from their industrial supplier.

    The keycard should be replaces with a go/nogo custom card

    Why in the world would you make custom tooling when there is a readily available off the shelf solution? You can just buy packs of keycards for dirt cheap and they are going to be a known thickness because they need to be to keep working in the same keycard slots. That thickness should be documented somewhere but it isn’t going to be in the manufacturing instructions because the production people don’t need it; they just need to know that the go/nogo gauge (the keycard) should fit. The more extraneous information you include on manufacturing instructions the greater the chance you have of someone missing or misreading something. If someone needs that extraneous info or something on the production floor isn’t right that’s when you bring in the engineer or process support staff who will have access to that info and the authority to make decisions based on it. If your production staff are making critical decisions on their own then something is very wrong with your manufacturing instructions (which sounds like the real problem here).
