Product Description

Keywords:Single Side Immersion Gold PCB, Single Side Plating PCB, Manufacturing Process of Single Sided PCB

Immersion Gold is a kind of PCB surface treatment process. Other processes include: Immersion Tin, Immersion Silver, HASL, lead-free HASL, ENIG, Flash gold, Thick gold, Selective gold plating, OSP, Selective OSP /HASL, etc.

The purpose of immersion gold process is to deposit nickel gold coating on the surface of the Printed Circuit Board (such as single-sided printed circuit board, double-sided PCB, Multilayer PCB, Rigid PCB , etc.) with stable color, good brightness, flat coating, and good weldability. It can be basically divided into four stages: pre-treatment (degreasing, micro etching, activation, post leaching), nickel deposition, gold deposition, post-treatment (waste gold washing, di washing, drying).

The thickness of immersion gold is 0.025-0.1um.

The immersion gold is a chemical deposition. A layer of coating is formed by a chemical oxidation-reduction reaction. Generally, the thickness is relatively thick. It is one of the deposition methods of the chemical nickel gold layer, which can achieve a relatively thick gold layer.

In the practical application of products, 90% of them are immersion gold board, because the poor weldability of plating gold plate is his fatal defect, and it is also the direct reason for many companies to give up the gold plating process!

Gold is used for surface treatment of circuit board because of its strong conductivity, oxidation resistance and long service life. General applications such as button PCB, gold finger PCB, etc., and the most fundamental difference between gold-plated PCB and immersion gold PCB is that gold plating is hard gold (wear-resistant), and immersion gold is soft gold (non wear-resistant).

Why to use immersion gold PCB

The immersion gold PCB mainly has the following characteristics:

1. The crystal structure of immersion gold is different from that of gold plating. The thickness of immersion gold is much thicker than that of gold plating. The immersion gold will be golden yellow, more yellow than that of gold plating (this is one of the methods to distinguish gold plating from immersion gold), and the gold plating will be slightly white (nickel color).

2. The crystal structure of immersion gold is different from that of gold plating. Compared with gold plating, immersion gold is easier to weld and will not cause poor welding. The stress of the sinking plate is easier to control, which is more conducive to the processing of the bonded products. At the same time, it is because the immersion goldis softer than the gold plate, so the gold finger made of the immersion goldis not wear-resistant (the disadvantage of the immersion gold).

3. There is only nickel gold on the solder pad of the immersion gold PCB Board , and the signal transmission in the skin effect is that the copper layer will not affect the signal.

4. The crystal structure of immersion gold is more compact than that of gold plating, which is not easy to produce oxidation.

5. With the increasing requirements for the processing accuracy of the circuit board, the line width and spacing have reached below 0.1mm. Gold plating is easy to produce short circuit. Only the pad of the immersion gold board has nickel gold, so it is not easy to produce a short circuit of gold wire.

6. Only the pad of the immersion gold plate has nickel gold, so the combination of the resistance welding and the copper layer on the line is stronger. The project will not affect the spacing when making compensation.

7. For the boards with high requirements, the flatness is required to be good. Generally, the immersion gold is used, and the phenomenon of the black pad after assembly will not appear. The flatness and service life of the immersion gold is better than that of the gold plate.

What is Single Sided PCB

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 Manufacturing

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

Construction of Single Sided PCB | JHYPCB

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
