High-Quality Single-Sided PCBs with Competitive Pricing
Introduction of Single sided PCB
At present, the printed circuit board is very significant to our life and appears in almost every aspect of our life. The printed circuit board first appeared in 1936. It was made by Mr. Eisler from Austria, and the finished product was a radio.
So far, electronic products have got rid of complicated wiring, because when there was no printed circuit board, the components were connected by complex wiring. For products with high difficulty and complexity, the disorder of wiring is a huge problem, which has been solved since the emergence of the printed circuit board.
There are many kinds of printed circuit boards. Single sided PCB should be the most simple printed circuit board, but it is widely used in consumer electronics, which has enormous demands.
Today we will introduce one of them, single-sided printed circuit board, which is most simple type of PCB boards. Please contact our sales team any time to get a free single sided PCB price.

History of Single Sided PCB
The original country of origin of the single sided PCB came from the United States, probably in the 1950s, which was also the period of the most vigorous development of the single sided PCB.
Although the country of origin was the United States, Japan had a historic innovation in production. Japan developed a paper phenolic copper foil substrate based on the initial copper foil etching and maintained sustainable development. Finally, various resin materials with stronger insulation and heat resistance, and less deformation were further developed, such as glass fiber epoxy resin, and so on.

Frequently Asked Questions
1. Half-year maintenance: The dust on top of the single-sided PCB needs to be cleaned every three months. We need to use a special cleaning solution to clean it. After cleaning the dust, we should use a hair dryer to dry the board in time. If we let the board dry on its own, it may cause damage to it.
2.Annual maintenance: In addition to cleaning the dust during the half-year maintenance, we also need to check the dust at the normal time. As long as there is dust, we need to clean it in time.
The advantages of single sided PCB incuding:
The design of single-sided PCBs is easy.
The manufacturing of single-sided PCBs is rapid.
The cost of single-sided PCBs is low.
The turnaround of single-sided PCBs is quick.
The difference between double-sided PCBs and single-sided PCBs is that there are circuits on only one side of single-sided PCBs, while there are circuits on both sides of double-sided PCBs, with vias to connect the circuits of the double-sided PCBs. The production process of double-sided PCBs is different from that of single-sided PCBs. There is a step of sinking copper which is the process of conducting the circuits on both sides in the production process of double-sided PCBs.
Double-sided PCBs and single-sided PCBs can be distinguished by their appearance. In brief, ingle-sided PCBs have only one routing layer. Double-sided PCBs have two routing layers, with vias in the middle. This is the most basic difference between single-sided PCBs and double-sided PCBs.
The best way is to design a single-sided PCB with the following parameters in mind.
The minimum distance between two vias (edge to edge) is 1mm.
The minimum distance between the hole edge of the punch and the adjacent circuit should be more than 0.3mm.
The clearance of the v-cut should be at least 24mm.
The minimum distance between the v-cut groove and the external shape should be 4mm.
The distance between the center line of the v-cut and the circuits is at least 0.4mm.
The minimum circuit distance of a single-sided PCB is 0.2mm.
The minimum distance between the edges of the pads is 0.25mm.
The minimum distance between the circuit and the edge of the pad is 0.2mm.
The minimum distance between the board’s edge and the circuit is 0.4mm.
The minimum distance between the circuit and the fracture aperture is 2mm.
The minimum distance between the solder-proof points and the circuits is more than 0.15mm.
The minimum distance between the solder-proof points is more than 0.25mm.
The following mistakes when handling a single-sided PCB will affect the function of the single-sided PCB.
The process of film application: The film is not firmly applied, resulting in the appearance of bubbles.
The exposure process: The scratched negative causes a local underexposure.
The development is blurred and unclear.
The etching process: The pressure of the nozzle is too high and the etching time is too long.
Problems related to plating: The plating is uneven. The surface has an adsorption force when plating.
Improper operation: In the production process of the single-sided PCB, the board is scratched and the circuits are broken due to improper operation.
Single sided printed circuit board has one copper layer as conductors, and double-sided PCBs have two copper layers with PTH vias normally.
Products such as power supplies, relays, sensors, led, printers, coffee machines and electronic toys use single-sided PCBs.
If the components are placed on one side of the board and the circuit is placed on the other side of the board, this kind of PCB is a single-sided PCB.
As mentioned above, a single-sided PCB is a printed circuit board containing only one layer of conductive material.
The single-sided printed circuit board is the most basic starting point for printed circuit technology. It plays an important role in the industry for low-cost, high-volume production of simple circuits.
Both single layer PCB board and single sided PCB board are same, all means printed circuit boards with only one copper layer.
Single sided printed circuit boards are widely used in consumer electronics, such as LEDs, power PCB, white electronics such as TV, air conditioner, cooker, refrigerator etc.
