What should the underside of a circuit board look like should the solder be flat spots or sharp points?
The solder joints should be convex and shiny.
What is flux remover?
When circuit boards are assembled, the parts are soldered on. In order for the solder to make a good connection to the parts and to the board, a substance called flux is mixed into the solder. It removes oxidation and cleans up the surfaces of the different parts so that the solder can stick to them. After the board is assembled, there is still flux on the board. Flux remover dissolves the flux and washes it away.
Insulating board containing conductive tracks for circuit connections?
printed circuit board
What is a big circuit board that has smaller circuit boards plugged into it?
the answer is the mother board of the computer
Why is it not suitable to use a soldering gun to solder modem electronics component?
Solder guns as a rule have wider tips than soldering irons/soldering pens.You might not be able to reach just the spot that you want to with a solder gun given the size of the components, and how tightly packed they are on a modern circuit board. Many modern components, such as integrated circuits, will be damaged by the high heat levels produced by soldering guns.

What does a solder do?
Removes solder from electronic components so that they can be removed from the circuit board
How do you connect a chip into a circuit board?
i think you solder it on :)
How tin used for in a mobile phone?
Tin could be in a mixture with lead to form the solder. Solder is used to hold the components to the printed circuit board.
What are the two alloys used to construct electronic circuit board solder?
Tin and Lead solder is the most common. The international trend is changing as the EU nations are moving toward non lead based solder.
What is the difference between reflow soldering and wave soldering regarding lead free alloys recommended by NEMI?
In reflow soldering, the solder is applied as a 'solder paste' typically by using a stencil mask and a squeege. The solder paste contains both a solder flux and the solder in the form of minute solder balls. The solder paste operation is done BEFOREadding the components to the board. The board is then passed through a reflow oven at which time, the solder paste melts to complete the soldering of the components to the circuit board. The reflow oven will have several heating zones designed to preheat, activate the flux, reflow the solder, and cool the board. The oven is setup so the components receive as little thermal shock as possible, and spend only a few seconds above the solder melting temperature.In wave soldering, the components are placed on the board. THEN the board is placed in the wave soldering machine. Typically the first step in the wave solder, the bottom of the board passes through a fluxing operation which either sprays flux on the bottom or passes the bottom of the board through a flux foam. After the flux, the board will usually pass a pre-heater to activite the flux and pre-heat the board for the soldering. Then, the bottom of the board is passed through a molten solder wave (looks like a smooth waterfall only consisting of molten solder). Afterwards, there will be a stage of cool-down.Some details of the process vary by how expensive the oven or wave-solder machine is, the complexity of the circuit board involved, for what kind of volume the production line is intended for, and how 'mil or space qualified' the circuit board is.
Suppose you experience laptop failure due to a broken solder joint on the circuit board What should you do to ensure that this doesn't happen again?
Acclimatize the laptop to room temperature before use
How do you replace the odometer cable for a 1994 LeBaron?
Shouldn't be a cable. It should be electronically driven from ECM. Mine didn't work until I repaired bad solder connections on the circuit board.
What are veroboards?
Veroboards are like breadboards, but you do have to solder. Its basically a circuit board. Heres a link http://www.smspower.org/smsreader/verotop.jpg

Why won't the glow plug light work on a peugeot 306?
I had this problem and it was broken solder on the timing circuit board for the glow plugs
2002 buick century gear shift light?
check solder connections on circuit board to resisters in upper right corner, 4 of them.
