Whether the PCB can be traced at an acute angle, the answer is no, as a result of that, the requirement for Reverse Engineer PCB Board With Acute Angle is existed. Regardless of whether the trace at an acute angle will have a negative impact on the high-speed signal transmission line, from the aspect of PCB DFM (design for manufacturing) alone, it is necessary to avoid the situation of sharp-angled wiring.
Because the sharp angle formed by the intersection of the PCB wires will cause a problem called acid traps. The acid traps on the pcb board here are an annoying thing. In the PCB manufacturing process, in the etching process of the PCB circuit, the “acid traps” will cause excessive corrosion of the PCB circuit and cause the problem of virtual disconnection of the printed circuit board.
Although, we can use CAM 350 to perform DFF Audit to automatically detect potential problems of “acid traps” to avoid processing bottlenecks during PCB manufacturing. If the PCB factory technicians detect the existence of acid traps, they will Simply paste a piece of copper into this gap. Many engineers in PCB board factories do not actually understand circuitry scheme layout.
They only repaired the acid trap from the perspective of PCB card reverse engineering and processing, but whether this repair will bring about further signal integrity problems. It’s not known, so we should try to avoid acid traps from the source in the PCB layout design.
