What is chip soldering?
when solder IC chips on printed circuit cards
Is the use of a soldering gun on printed circuit boards recommended?
In general no because its easy to overheat the board and lift pads or even entire traces.However where the board has large areas of copper soldered to metal chassis lugs, if you need to unsolder such connections the only tool likely to be able to apply enough heat is a soldering gun.
Can you use a printed circuit board on an embedded system?
I cannot imagine a modern embedded system that is not built on a printed circuit board.
What printed circuit board is the most important circuit board in the computer?
The motherboard aka mainboard
What liquid will dissolve a printed circuit board?
Ferric Chloride
What precautions should be observed when soldering printed circuit boards?
Never use a acid core solder only resin core should be used and keep the temperature of the soldering iron as low as possible 250 deg C max soldering should be done in a well ventilated space.

What do you mean by wave flow soldering?
Wave flow soldering is a method of soldering all the connections on a printed circuit board in a single step on a machine (instead of one at a time by hand).A wave flow soldering machine has the following parts:a heated tank containing molten solder covered with a thin layer of fluxone or more printed circuit board fixturesa mechanical wave generatorPrinted circuit boards are populated with components (on automatic part placement machines and/or manually by human assemblers). The populated printed circuit boards are placed in the fixtures. As each fixture goes into the wave flow soldering machine the wave generator sends a wave of solder down the length of the heated tank. The top of this wave just touches the bottom of the printed circuit board, soldering all the connections. After the fixtures leave the wave flow soldering machine they are allowed to cool a while and the printed circuit boards are removed.The soldered printed circuit boards are then washed to remove any flux residue left by the wave soldering machine, then sent to be tested to make sure they function as intended.Wave flow soldering works best for "through hole mounted" components.
What are the four steps for correctly soldering components to a printed circuit board?
1. Remove the soldering iron from the holder and wipe the tip on a sponge. 2. Heat the joint to be soldered. 3. Apply solder to the joint. 4. Apply a small bit of solder to the tip of the soldering iron and return it to the holder.
What kind of job is a PCB job?
A PCB job is one that is involved in the light manufacturing of Printed Circuit Boards (PCB's). This tends to involve soldering and light assembly of electronic goods.
A Job in PCB Designing?
printed circuit board printed circuit board
When was Printed Circuit Corporation created?
Printed Circuit Corporation was created in 1961.
What precautions should be observed when using household materials?
There are many precautionary measures in household materials that you can take. One of these measures is to lock cabinets with chemicals.
What has the author Mike Judd written?
Mike Judd has written: 'Soldering in electronics assembly' -- subject(s): Design and construction, Printed circuits, Solder and soldering
What are the uses of De-solder Guns?
De-soldering gun is used for removing molten solder, defective components, altering, and salvaging high value components in a circuit for possible re-use.
Is the use of a soldering gun on printed circuit boards recommended?
In general no because its easy to overheat the board and lift pads or even entire traces.However where the board has large areas of copper soldered to metal chassis lugs, if you need to unsolder such connections the only tool likely to be able to apply enough heat is a soldering gun.
Why the components not fell down in case of wave soldering?
During wave soldering, components are held in place by surface tension of the solder. As the printed circuit board moves over the wave of molten solder, the surface tension of the solder keeps the components in position until the solder solidifies, preventing them from falling off. Additionally, the design of the PCB and components ensures proper alignment and stability during the wave soldering process.
