Surface mount components

So one solution is to go to the manufacturer and get a new board, this could be a lot more expensive than anticipated, the other option is to find a circuit that does the same thing, using "normal" components, make a pcb, build it up and give that as a substitute. The latter is not always a viable solution in the more complex applications, but many of the systems I have to fix are basically the power supply boards. This is probably the most obvious pcb one can substitute. (For this reason I have a variety of power supply pcb's ranging from single to dual supplies, low voltage to high voltage regulation) Many of the single chip regulators do not tollerate more than 30 volts, so alternative solutions have to be sought.
Your normal soldering iron is also totally inadequate, you will need a lens so that you can see what you are doing, each soldered joint has to be meticulously inspected to ensure a good joint. (This is done with normal components as well, but it takes much less time.)
Some time ago I priced a setup to do multipin (square chips with more than 20 pins) soldering, and it was the price of a motor car, but there would be no mistakes or bad soldering with this system.
If any one has found a viable way of doing SMD soldering, pleas let us know where and how much it is, until then let us stick to the normal component projects.

Rush PCB engineers work with their customer, throughout the initial design and development process to assure manufacturability, product quality, and consistency. Along the way, on-line assistance is provided by RUSH PCB Inc with:
- Impedance Calculator – important for higher speeds
- to help with circuit routing
- Design for Manufacturability (DFM) – to help make sure the layout will work properly in the assembly and manufacturing process
