An Overview On Printed Circuit Board Assembly
We all know that in order for a gadget or equipment to work, it has to be connected to an electric source. However, not many of us know that in order for these devices to work, they need to have a printed circuit board. A printed circuit board or PCB is used to electrically connect and mechanically support electronic parts using conductive pathways and signal traces that are etched from copper sheets that are laminated to turn into non-conductive substrate. A PCB that is filled with electronic parts is called printed circuit board assembly. They are usually made from fiberglass or ceramics. All electronic devices or gadgets require a printed circuit board assembly in order for them to work. In addition, all electronic components of a device can't just be put into the phone. They need a foundation to sit on and that's how a PCB printed circuit board works. It serves as a strong base for every part and conductive pathways in an electronic gadget.
In order for the printed circuit board to form, there are actually two processes that are used for it. The first process is the through-hole construction wherein the component leads are inserted in holes. The other process used in making printed circuit board assembly is the surface-mount construction in which the components are situated on pads located on the outward surfaces of the printed circuit board. These two processes have component leads where they are fixed electrically and mechanically to the board through a metal solder that has melted. To further understand how printed circuit board assembly works, there are various methods in soldering that are being used for the PCB components to connect. When it comes to mass production of a printed circuit board, it's crucial that it must be done through machine placement or bulk wave soldering types, to ensure that there are no mistakes in soldering them. However, if there is only a number of PCB assembly that is needed, expert technicians are able to solder very small parts by their own hand and under a microscope. This is done with the use of a soldering iron with fine tip and tweezers that are designed for small volume prototypes.
After the parts of the PCB have been soldered, it will have conformal coating that is either dipped or sprayed. This coat helps to prevent corrosion and leaking of current shorting due to condensation. It's also important for one to know that printed circuit board assembly is very sensitive to static so it should be placed in bags that are antistatic while it is being transported or shipped. If improper techniques are applied to it, it could transmit static charge to the board and may damage the component.

What type of solder can I use to solder silver to fine stainless steel?
I have some 8mmx10mm silver bezels that I want to solder to a fine stainless croos steel and mount black star sapphire stones on the front of this 2"x3" necklace cross for my wife .I have great faith in all my community friends.Help!!!! LOL BOB
Use "easy flow" type silver solder. Note that this is a kind of solder specifically used for jewelery, I'd advise against using general-purpose silver solders. You can buy this type from online jewelry supply companies.
The stainless steel should be cleaned with fine sandpaper immediately prior to soldering. This removes the protective oxide layer that would normally prevent the solder from bonding. For this reason, an acid-type flux should be used. Be sure to clean the piece thoroughly with hot soapy water to remove the flux residue after you're done.
