Because prototyping was an early adoption of Manufacture and Assembly Design (DFMA), the PCB assembly process has many benefits in the long run.

In PCB manufacturing, suitable materials for a particular type of PCB are selected during prototyping. Ni igbesẹ yii, awọn ẹlẹrọ ṣe idanwo ati gbiyanju ọpọlọpọ awọn ohun elo ṣaaju yiyan ti o tọ.

Often, if a PCB design error is found during production or assembly or even operation, the designer must start from scratch. Often, reverse engineering is required to check for errors in manufactured PCBS. Atunṣe ati atunkọ yoo padanu akoko pupọju.
