Jan 01, 2019 As illustrated in Fig. 2, the machines are arranged in a production line based on the process chain of manufacturing in a factory where the environmental conditions, such as temperature, vibration and humidity, may not be strictly controlled.On the other hand, surface measuring instruments are located in different places in the factory for measurement of the

What is Surface Finish in PCB Manufacturing?

Mar 03, 2021 In circuit board manufacturing, the process of implementing the PCB surface finish is critical in enhancing the reliability and shelf life of the PCBA.We will cover the various types of surface finishes the printed circuit boards are given to enhance good inter-metallic bonding and the shelf-life of the assembly.. Current-day PCB assemblies consist mostly of

Typical Tolerances of Manufacturing Processes

Figure 15.8 shows relative production time as a function of surface finish for common manufacturing processes. Although the curve for each process is slightly different, the ge neral trend shows that the relative production time increases exponentially as a function of achieved surface finish. In other words, doubling the surface finish
