Страница 2: ...u should be able to solder ICs without destroying them Accuracy and neatness is more important than speed Get it working first time These instructions will guide you but I assume you are familiar with basic techniques and equipment The instructions should be suitable for someone with a skill level appropriate to the project All components except batteries are mounted on the circuit board no slow f...
