Go slow Hands-on: Soldering 34 Step 21: Verify solder joints and check for solder bridges Step 22: Install 9V battery clip to board Hands-on: Soldering 35 Step 23: Flip board over and solder battery leads Hands-on: Soldering 36 Step 24: Attach test battery and watch what you made NOTE: If it doesn’t work, detach battery immediately and have it inspected Hands-on: Soldering 40 When completed, please wait for further instruction Hands-on: Soldering 38 Colorado Space Grant Consortium Questions? Board Safety: Reading a Resistor: The resistors in this workshop have already been organized by value. In the event that your resistors get mixed, please refer to the chart at the left to classify your resistors, or use your multimeter. If you are unsure, don’t hesitate to raise your hand and ask for assistance. Pre-Bending: Pre-Bending 101: Pre-bending is a technique that allows components to be easily inserted into a PCB. Pre-bending also allows components to lay more flush with the board. Bending components to the correct bend radius takes practice, but mastering the technique will reap rewarding benefits! Pre-Bending: Pre-Bending 101: Start with the bending and prodding tool in the position shown in the top picture. Choose a location along the length of the tool that will yield the appropriate bend radius. Use your thumb to bend the lead such that the component and lead are orthogonal. 90° Hands-on: Soldering 14 - Get into your teams - Each person on the te
