#93691 - First hand about prototyping in America Responding to: ???'s previous message |
By far and large the biggest percentage of the market for prototyping boards in the USA, that are similar to Veroboard products, is supplied by a company called Vector Elecronics Inc. They have a range of available types of copper patterms on their boards including strip line types. You can view the various types at the link given below. This links to a DigiKey catalogue page that lists the Vector products.
http://dkc3.digikey.com/PDF/T052/1367.pdf It is VERY common for engineers and technicians here to refer to prototyping board material as "vector board". I have tried many of the types of Vector's prototyping boards over many years and have found the pattern called B1/B2 to be the best to use. This type has fully plated through holes with round pads on both sides. All the holes are gridded at a spacing of 2.54 mm. When using this type of prototyping board the components can be installed and soldered securely in place. Small gauge wire is then used to connect the circuit per the schematic. I often use 20 ga or 22 ga solid bare tinned copper wire to hook in PWR and GND connections. I use a small diameter nylon or TFE tubing that comes on a roll and is cut off to needed lengths to insulate these PWR/GND buss wires as they are installed. For connecting the signals together I typically use 30 ga solid wire that has Kynar insulation that is cut and stripped and then soldered in place as needed. With care it is possible to make prototypes that can even work at "video" frequencies or very low level analogue circuits. Here is an example of one thing I built using B1/B2 type Vector board. This was a quick DIP-40 to PLCC-44 adapter that I threw together once when I needed to program some Intel 87C51FA parts a few years ago using my Bytek ChipBurner Universal device programmer.
