Circuit construction


1. Tag strips and group boards are used in:




2. It is necessary to test and refine a new but fairly simple circuit design. The most suitable construction method would be:




3. At very high frequencies it is necessary to:




4. The acronym SRBP stands for:




5. The developer used when producing a photo-etched PCB is:




6. Photo-resist board is exposed by placing it:




7. The etchant commonly used for printed circuit manufacture is:




8. The drilling diameter for a PCB is usually:




9. Electronic solder has a typical melting point of:




10. A power transistor dissipates 20W and has a maximum junction temperature of 75 deg.C. If the maximum ambient temperature is 35 deg.C what is the maximum value of total thermal resistance that should be used?
