Single Sided Hot Air Solder Leveling Circuit Board

Keywords：Single Sided PCB Fabrication, Single Sided PCB Fabrication Process, Custom PCB Single Side

Hot air solder leveling is a step and technological process of PCB production. PCB manufacturing process includes immersion gold, immersion silver, OSP, etc. In particular, the tin spraying process is to immerse the PCB into the molten solder pool, so that all exposed copper surfaces will be covered by solder, and then remove the excess solder on the PCB through the hot-air cutter. Because the surface of the printed circuit board and solder paste are of the same kind, the welding strength and reliability are better. However, due to its processing characteristics, the surface flatness of tin spray treatment is not good, especially for small electronic components such as BGA, due to the small welding area, if the flatness is not good, it may cause short circuit and other problems, so a better flatness process is needed to solve the problem of tin spray plate. Generally, the immersion gold process (it is not gold plating process) will be selected, and the principle and method of chemical replacement reaction will be used for reprocessing to increase the thickness of nickel layer of about 0.03-0.05um or 6um, so as to improve the surface smoothness.

Jinghongyi PCB is one of the many PCB manufacturers and suppliers in China, especially good at the manufacturing and fabrication of single-sided printed circuit board（have a hole or no hole）, double-sided PCB and Multilayer PCB. The company has been engaged in PCB manufacturing for nearly 10 years, and has rich experience in the production of single-sided PCB and double-sided PCB. Due to the continuous expansion of electronic product market, PCB application market has also been vigorously developed. So single and double sided PCB is also one of the most common PCB types we see. As a result, we produce the most single-sided and double-sided PCBs, so we constantly improve the manufacturing process and do everything possible to reduce costs for customers. Therefore, our single-sided PCB price is also the lowest. Our advantage is not only reflected in the price advantage, but also we can provide you with the production of PCB prototypes, small and medium-sized batches and PCB assembly services.

Our aim is to provide customers with the best cost-effective products and services. At the lowest cost, we also guarantee the best quality of your products. Therefore, we choose FR4, phenolic paper base plate, CEM-1 and CEM-3 composite copper clad plate and other materials, mainly according to the needs of customers or to specify which materials to use.

In addition, our experienced engineers can provide you with product manufacturability inspection and PCB design assistance. You just need to provide your Gerber files.

Single Sided PCB Definition

Single Sided PCBs, also called Single Layer PCB, contain only one layer of conductive material and are best suited for low density designs. Single sided PCB'S have been around since the late 1950s and still dominate the world market in sheer piece volume. Single-sided printed circuit boards are easily designed and quickly manufactured. They serve as the most cost effective platform in the industry.

There are many similarities and differences between single sided PCB and double sided PCB, and we will also explain them here.

Single Sided PCB Manufacture

One thin layer of thermally conductive but electrically insulating dielectric is laminated with copper. Soldermask is usually applied on top of the copper.

JingHongYi PCB (HK) Co., Limited is a professional Single Layer PCB manufacturer from China. We have a very efficient and complete production process. To learn more about our PCB production process, click here: PCB manufacturing flow chart.

JHY PCB produces prototype, midrange and high volume Single Sided circuit boards, with a copper thickness from 1 to 20 ounces. Operating temperatures range from 130 C to 230 C. Single sided boards are available with surface finishes including Organic Surface Protectant (OSP), Immersion Silver, Tin, and Gold plating along with both leaded or lead-free Hot Air Solder Level (HASL).

Construction of Single Sided PCB

The base material, which is also named as substrate, is composed of insulating fiber glass which gives PCB strength and compact look. The nature and type of base material defines if board is going to be Flexible PCB or Rigid PCB.

Above substrate, there lies a copper layer which provides conducting path for various components on the board. The copper thickness is different for different boards depending on your needs and requirements and is defined in ounces per square foot.

On the top of copper foil, there exists a solder mask layer. This layer is mainly used for protection and makes the copper foil insulating which helps in avoiding the conduction in case direct contact happens with some conducting material.

On the top of all layers, there exists a silkscreen layer that is mainly used for adding symbols and characters on the board so a common person can anticipate the clear understanding of the board.

Advantages of Single Layer PCB

• Ideal for simple low-density designs
• Lower cost, especially for high volume orders
• Lower probability of manufacturing issues
• Popular, common, and easily understood by most PCB manufacturers

Application of Single Sided PCB

Aluminum PCB, LED PCB used in LED lighting industry are basically Single Sided PCB.

ALTHOUGH SINGLE SIDED PCBS ARE RELATIVELY SIMPLE, THEY CAN STILL BE USED IN VERY COMPLEX DEVICES:

• Power supplies
• Relays (automotive and industrial)
• Timing circuits
• Sensor products
• LED lighting
• Radio and stereo equipment
• Packaging equipment
• Surveillance
• Calculators
• Printers
• Coffee makers
• Vending machines
• Solid state drives
• Camera systems

Single Sided PCB or Double Sided PCB?

PCBs are more suitable for project design as compared to double sided PCBs and vice versa.

Before you pick any type of PCB for your project, you must take one thing into consideration that single sided PCB layouts are more difficult to route as compared to double sided PCB, but following are the reasons why you should put an effort for making and picking single sided PCB over other PCBs.

• If you are hobbyist or students, and concerned to make PCB at home, you must know, developing single sided PCBs at home are much easier than developing double sided PCBs at home.

• As you are a manufacturer and very much interested to keep your cost down and producing a single sided PCB a most economical process. In terms of cost, producing single sided PCBs are more economical than producing double sided PCBs.

• Almost all HVAC systems make use of single sided PCBs, because they are more reliable and cost effective and don`t compromise the overall quality of the product.

• Using through hole technology in single sided PCBs still have its drawbacks and limitations because conductive layers, lines and pads stay on single side of PCB but it still is a cheap process to combine all components at one place. Multilayer PCB is also used in many applications where single sided and double sided PCBs fail to fulfill the requirements.
