    Two books on electronics help me to choose

    Re: Two books on electronics For the beginner Electronic principle by Malvino is excellent, as it give you detail but basic circuit analysis with minimum or very basic mathematics. Other book is also good but you go for it for the 2nd option.

    High quanlity or Mil standard PCB

    Thanks for the reply and your precious time. But please read carefully before you reply. I never write any thing like that I solder 10 to 30 minutes. I just wrote that number of times of solder. What I want a parameter like TG170, or one can say bonding strength between copper and boards. which...

    High quanlity or Mil standard PCB

    Thanks for the reply. It is double and multilayer. Actually I have both the PCB, one I got from manufacturer with FR4 TG170 and other my friend give for the sample, (he did not know the parameter). The soldering iron and the component used same for the both the boards, mine one pads peels off...

    High quanlity or Mil standard PCB

    Thanks for the quick and fast reply. Sorry I did not mentioned that I already made from FR4 TG170, but these boards has also not much higher number, although it is better than normal FR4, but I need higher than this.

    High quanlity or Mil standard PCB

    Hi, I want to inquire about the quality of the PCB. Normally PCB (FR4) their pads are peel off after two to three time of repairing (soldering). I have seen PCB which are being soldered for more than 20 times but never get their pads removed, with the same temperature. Kindly mentioned some type...
