PCBs or printed circuit boards are currently in a lot of demand among common electronic support devices. PCB support has a lot of added benefits as compared to the point to point construction due to its glass epoxy or copper board construction which is soldered together with etched portions, pads, tracks, as well as other electronic components. So majority of the PCBs are produced using an automated design check in the manufacturing process which also PCB fabrication.
How to select the perfect PCB?
Before moving further let’s have a glance at the components which are essential for selecting the PCB.
- PCB should be copper clad and made completely tolerant as per international standards.
- High quality of base material so that the board can have the capacity to conduct the flow of electrons which will determine the reliability factor of any PCB.
- Eliminating truck cut from a PCB.
- Impeccable neat and tidy PCB because even a speck of dirt on its surface could create any malfunctioning as well as poor connection.
- The hole wall thickness should be cladded with copper and thickness should be approximately 25 microns which tendency its capacity to resist expansion along its z-axis.
- The positional tolerance present on PCB also matters in terms of its functionality as well as the looks.
- Another thing to keep in mind is the thickness of the solder resist layer even though there are no specific provisions that are described in the international standards about the thickness of the solder is resistance but it must be tolerant enough so that it can support any kind of electrical insulation without fault.
- PCB fabrication is often done to ensure that surface treatment does not change matter logically over a period of time. But time to time treatments are required so that the shelf life increases and there are no chances of the PCB getting delaminated or has any circuit breaks.
- Most importantly one must purchase each part as per the predefined program because buying in bulk might lead to missing critical points which in turn will lead to erosion is designing eventually.
So, a highly reliable PCB manufacturer will keep in mind all the above technological aspects while designing the perfect printed circuit board.
Let’s talk about layers!
PCB for simple electronics comes with limited functions and is usually composed of a single layer whereas the sophisticated electronic devices require for multiple layers of PCB. Multilayer PCB has increasing complexity but it is impeccably a widespread choice of most of the electronic device manufacturers.
Most of the advanced electronic applications require four to eight layers which include smartphones as well as mobile devices which tend to use around twelve layers of PCB. In order to suffice such demands by advanced electronic devices, the PCB manufacturer invented the multilayer PCB.
They come in a wide range of sizes as well as thickness to accommodate the needs of the changing applications which also support certain variants ranging from four to twelve layers. Multilayer PCB is also cost-efficient which packs the power of a double layer PCB into a design that is also a fraction of the size. There are numerous benefits of using a multilayer PCB which include its small size, increased durability, enhanced flexibility, more power-packed performance, high quality and most importantly the lightweight construction.
So, without any further ado, it is high time for interested people to head straight towards a reliable PCB manufacturer but does not forget to check ok the critical components which make a PCB reliable.
