　　UNS2880b-P,V2 3BHE014967R0002 PCB组装是一个涉及多个步骤和关键因素的复杂过程。以下是关于PCB组装过程的详细概述：

　　PCB组装步骤

　　添加焊膏：

　　这是组装过程的最初始阶段。

　　在需要焊接的地方将焊膏添加到元件焊盘上。

　　焊膏通过焊屏的帮助粘贴在正确的位置，焊屏由PCB文件制成并带有孔。

　　放置组件：

　　UNS2880b-P,V2 3BHE014967R0002 在焊膏添加到组件焊盘后，开始放置组件。

　　PCB通过一台机器，该机器将组件精确地放置在焊盘上。

　　焊膏提供的张力将组件固定在适当的位置。

　　回流炉：

　　将组件放置在板上之后，PCB穿过回流炉传送带。

　　烤箱的受控热量使第一步中添加的焊料熔化，从而永久性地连接组件。

　　波峰焊：

　　使PCB通过熔化的焊料波。

　　这在焊料、PCB焊盘和组件引线之间建立电连接。

　　UNS2880b-P,V2 3BHE014967R0002 PCB assembly is a complex process involving multiple steps and key factors. Here is a detailed overview of the PCB assembly process:

　　PCB assembly steps

　　Add solder paste:

　　This is the very beginning of the assembly process.

　　Add solder paste to component pad where solder is required.

　　The solder paste is pasted in the correct position with the help of the solder screen, which is made of PCB file and has holes.

　　Place components:

　　UNS2880b-P,V2 3BHE014967R0002 After the solder paste is added to the component pad, start to place the component.

　　The PCB passes through a machine that places the components precisely on the pad.

　　The tension provided by the solder paste holds the assembly in place.

　　Reflux furnace:

　　After placing the assembly on the board, the PCB passes through the return furnace conveyor belt.

　　The controlled heat of the oven melts the solder added in the first step, permanently connecting the components.

　　Wave soldering:

　　Pass the PCB through a molten solder wave.

　　This creates an electrical connection between the solder, the PCB pad, and the component leads.
