HDI PCBs, one of the fastest growing technologies in PCBs, are now available at PCBSky. HDI PCBs contain blind and/or buried vias and often contain microvias of .006 or less in diameter. They have a higher circuitry density than traditional circuit boards. There are 6 different types of HDI PCBs, through vias from surface to surface, with buried vias and through vias, two or more HDI layer with through vias, passive substrate with no electrical connection, coreless construction using layer pairs and alternate constructions of coreless constructions using layer pairs. HDI any-layer printed circuit boards are the next technological enhancement of HDI microvia printed circuit boards: all the electrical connections between the individual layers consist of laser-drilled microvias. The main advantage of this technology is that all the layers can be freely interconnected. To produce these circuit boards, PCBSky uses laser-drilled microvias electroplated with copper.

Hard Gold PCB , immersion gold pcb, is to immerse the board in the plating tank and apply current to form a nickel-gold coating on the copper foil surface of the board. The electro-nickel gold is characterized by high hardness, wear resistance and oxidation resistance. Widely used in applications. Introduction to Hard Gold PCB Technology: 1. Purpose and role: gold as a precious metal, has good weldability, oxidation resistance, corrosion resistance, small contact resistance, good wear resistance of the alloy and so on; 2. At present, the electroplating gold of the circuit board is mainly a citrate gold bath, which is widely used for its simple maintenance and simple and convenient operation; 3. Water gold content is controlled at about 1 gram / liter, PH value of about 4.5, temperature of 35 degrees, specific gravity of about 14 waves, current density of about 1ASD; 4. The main added drugs are acid-adjusted salt and basic-adjusted salt for adjusting pH value, conduct...

Electroplating can be divided into hard gold and soft gold. Hard gold electroplating is an alloy, so its hardness is relatively hard. It is suitable for use in places requiring force and friction. It is generally used as the edge contact point of PCB (commonly known as golden finger). Soft gold, On the other hand, is commonly used to connect aluminum wires On the COB (Chip On Board) or On the touch surface of mobile phone keys, and more recently, it is widely used On both sides of BGA boards. The distinction of hard gold and soft gold, it is the component of this layer of gold that goes up finally plating, when gold-plating can choose electroplate pure gold or alloy, because the hardness of pure gold is softer, so also call "soft gold". Hard gold plating PCB  has excellent electrical conductivity, wear resistance, oxidation resistance and reduced contact resistance. But gold is extremely expensive, so it is only used for topical gold plating or chemical gold on goldfinger.  H...

Function of auxiliary components in   hard gold plating PCB   plating solution: Boric acid ACTS: as a buffer, which can maintain a relatively balanced PH value of hard gold-plated PCB plating solution with a concentration of 35~55g/l; Nicke...

The purpose of   hard gold plating PCB   adhesive tape: is to expose only the part of the board to be plated with hard gold, and to cover the rest with adhesive tape to prevent plating. Tape sticking is a delicate work. It is not allowed to stick the golden finger with tape and it is too far away from the golden finger. It is necessary to prevent cutting the board when removing the excess tape and avoid wiping the flower artificially.  Pay attention to the use of tape not degumming phenomenon, in order to avoid the copper surface residual glue stains. This step is the most labor-intensive, automatic tape machine on the market, will bring about another industrial revolution.  The purpose of hard gold plating PCB roll adhesive tape is to stick the adhesive tape to the board surface through the roller machine, so as to avoid cross contamination between the cylinder of medicine caused by the Tibetan medicine water in the belt during the nickel-gold plating because th...
