A:How can I connect a resistor to a PCB without using a soldering iron?
It's far to small to solder accurately (it's much smaller than a normal resistor) and the intense heat would damage the board. What are my options? Please include links to where I can buy the necessary supplies.
Q:
that is a surface mount type. I have done them with a cheap soldering gun. But you gotta have great eyes and a bit of practice.
I did read somewhere that you can buy a rear defogger repair type of glue/solder that works. But i have no idea if i would count on it as i only read about it.
Its diffently trick to solder but it can be done.
A:What is the thickness of the conducting part in a PCB?
What are the material used in the making of PCB?
Q:
It varies with the requirement of the application. Board shops usually talk about "ounces of copper", having to do with the actual weight of material per square area. To convert from a couple of commonly used thicknesses:
1 ounce copper = 0.0014 inches = 0.0356mm
2 ounce copper = 0.0028 inches = 0.0711mm
Some standard finished thicknesses for boards are
0.031", 0.039" and 0.062" (0.8mm, 1.0mm and 1.6mm)
As far materials go, that is also variable, but there's a lot of commonality between most manufacturers. Here's a link that will show you some of the more commonly used materials and thicknesses, and how they typically stack multilayer boards:
A:How do you solder extremely small components onto a PCB (Printed Circuit Board)?
For example, how do you solder something like a microcontroller onto a conventional PCB ( the pins are 1mm apart). Should I solder the component under a microscope with an extremely small tipped soldering iron, or use a technique, e.g. wave soldering?
Thanks, any help will be greatly appreciated - as you can see I am a bit of a novice in the field of electronics!
Q:
I have done extremely small strain gage devices with the aid of a microscope and a small tipped iron. But it isn't easy. I could see that wave would work better for a production environment on PCBs. Stick to a small tip soldering iron but I would hardly think a microscope is necessary for something 1mm apart and my eyes aren't great. Heat the joint, then apply the solder. Always use a heat sink to stop the heat destroying the device you are soldering. Consider a socket for real sensitive devices so you cannot cook them. |
