The PCB surface finishing difference between HAL and ENIG

PCB surface finishing technology When surface finish (also called surface coating) defined to a PCB it means an intermetallic joint between the exposed bare copper of the solder-able area of the circuit board and the electronic components, this excluding the area of solder mask. Printed circuit boards without a protective coating would be susceptible to … Continued

PCB-manufacturing-specification

What is the difference between IPC-6012, IPC-A-600, and IPC-A-610?

Specifically, both specification of the IPC-A-6012 and the IPC-A-600 are guiding documents made for the bare printed circuit boards. IPC-A-600: is a specification and document for the inspection criteria of PCB, which is a the visual representation of the IPC-A-6012 document. IPC-A-6012: is a guiding document for the PCB manufacturing process. IPC-A-610: is a guiding document for the acceptability of … Continued

Discussion about common 4 layers PCB stack-up

Introduction: There are general discussions on the laminated structure of multi-layer printed circuit boards, and most PCB factories have relevant training about this knowledge, which have thoroughly and clearly explained various laminated stackup’s structures and principles. In this article we are mostly focusing on discussing the advantage and it’s weakness of the common 4 layers … Continued
