Thanks for the info. I am sorry that you have to spend so much of your time away from your family. Thankfully, I get to spend much more time away from work. I hope that you can slow down a bit. That is not fun to have to work that much.
Well one can't argue with that, Utimitely everything is horses for courses :-) I tend to do 20-30 designs per year all requiring small proto runs and seem to work some 18 hours most days which makes me I guess more time conscious than most when wanting to find time for family. I also very much value the time spent here sharing with others so I don't under estimate that value either. Usually 10-20 proto services per year. Sometimes a friend wants a board and I add it to the panel and depending on size they pay only a few $.
The company is called Entech, This link gives the full range of specs:
I appreciate the comment, though with my last 10 projects, I could fit all of them on your board and still have a lot of space left. I would still be out $200+ on the cost of the boards and I would not have been able to have them produced there because I have parts that require the 6/6 spacing that is offered.
I do get the point though that time is precious, but at the same time, it I spent all my time worrying about what I should be doing with my time, I would not have learned many valuable lessons of life by either the failures I had to solve, and hence take more time, or the successes that I have had because I would be worried I might waste my time in failure. There are costs associated with everything, like right now. I could be making dinner, showering, sleeping, or enjoying this sharing of differing viewpoints. All cost time and a lost chance to do something in the moment, but I decided on the last option as it gives me a chance to interact with someone as well as understand a different viewpoint.
By the way, which is the service you use. Always good to know of vendors that others would recommend.
I use a service that does 2 x 8"x10" of PCB material for $300 plus shipping. They do 7/7 track & spacing with 8thou vias and 0.2mm annular rings. I just put a dozen or so designs together on the panel. Includes BBT and DRC and I can get gold flash for an additional $50. $300-$350 might sound like a lot but 2 panels of 8"x 10" with as many designs as I want if I do the panelisation myself it's hard to beat for an all inclusive. Comes with both sides silk and mask. At the end of the day we have only so much time. We can always get more money but never more time.
Ah yes the opportunity cost of things in life. In this case, I lost perhaps 2-3 hours. To pay for a service that offered similar design limits for a proto board, I would have had to work a few extra hours, so it was probably a wash. Now, if I had my family with me while I was doing this, I would not have worried aobut it and spent time with them, but they were about 9 hours away when I was doing this, so it would have been this or perhaps watching an episode of NCIS.
Well that is of course fair enough, I just wonder whether the the savings are worth it when one considers that our time on earth is rather finite so that time becomes one of our most valuable commodities
Ah yes. I had though about perhaps not connecting a few of the outer connections to allow for some of the inner connections. This still could work if I did not need all the connections, I was just not that hard up on using the chip, but is something that I may yet consider if I really get to the point that I want to use it. Thanks for sharing!
The BGA that I routed was a Xilinx CPLD and only had two concentric rows of pads. I escaped the inner pads by routing thru (connected to) a pad on the nearby outer row. This cheat worked because I was only building the design to test my ability to solder BGAs. I used two separate loads of CPLD code where one or the other connected pads was tristated.
I've seen similar tricks work on large pin count BGAs where only a few of the balls connected to the die. Inner pads were routed thru external pads that were not connected to the part's die. Unfortunately it's a such a rare use case that it's almost useless.
