  • Place the largest 10 kΩ resistor (labeled 103) in the outline labeled R4 on the board.

  • For a handy surface-mount resistor value calculator, click here. All the resistors in this kit are 3 digit EIA (Electronic Industries Alliance).

  • Re-heat the solder while holding the resistor in its outline until the molten solder envelops the end (shiny) cap.

  • All the resistors through Step 13 are symmetrical and can be soldered in either orientation.

  • If the solder won't envelop the cap, add some flux or a little fresh solder and try again.

  • Remove the iron, then remove the tweezers once the solder has cooled.

将最大的10千欧电阻器（标有103）放置于电路板上标有R4的轮廓位置。

点击此处获取便捷的贴片电阻阻值计算器。本套件中的所有电阻均为3位数EIA（电子工业联盟）编码。

在保持电阻器位于其轮廓内的同时，重新加热焊料，直至熔化的焊料包裹住端部（光亮）的焊盘。

步骤1至13的所有电阻器均为对称结构，可采用任意方向焊接。

若焊料无法完全包裹焊盘，可添加适量助焊剂或少量新焊料后再次尝试。

先移开电烙铁，待焊料完全冷却后再松开镊子。
