5.Immersion Tin(I-Sn) Due to all solders are based on tin, the tin coating can match any type of solder. The surface finish immersion tin can form a flat between copper and tin, this feature enables the sinter to have the same good weldability as the hot air leveling, without the headache of the unfitness in […]

4.Electroless Nickel/Immersion Gold (ENIG) The general process of ENIG is: Acid cleaning -> micro etching -> presoaking -> activation -> electroless nickel -> immersion gold.There are six chemical channels in the process, involving nearly 100 chemicals, and the process is a little complicated. The ENIG is coated with a thick and electrically nickel-gold alloy that […]
2.Organic Solderability Preservatives(OSP) The general process of OSP process is: degreasing -> microcorrosion -> pickling -> pure water cleaning -> OSP coating -> cleaning.The process control is relatively easy to others. OSP is a process that meets the RoHS directive requirement for PCB surface finish. It has anti-oxidation, thermal shock and moisture resistance, which can […]
With the continuous improvement of the living environment, the environmental issues involved in PCB production are getting more and more attention, especially Lead and Bromine. The basic purpose of PCB surface treatment is to ensure good weldability and electrical performance. Because the copper is unlikely to remain the original for a long time exposed in […]
Voice technology has always had a prominent problem: you will feel a bit strange with yourself when you talk to someone. However, technology continues to rise under the people’s demands, people have less self-awareness of their machines when they in conversations. Any non-language device is an inevitable trend, it accomplishes work in a similar manner, […]
Since RCYPCB started to offer Multilayers PCB service, many customers usually ask us how to design a suitable layer stack-up for the boards. Let’s briefly give a tutorial for layer stack-up design. Firstly, we will expound on what the layer stack-up is. The high-speed development of electronics has been promoted the PCBs towards micronation, lightweight, […]
Thailand’s second-largest PCB maker Trident publishes an announcement in June, new orders and new customers continue to inject, coupled with ongoing new PCB factory capacity out, monthly revenue soared high, reaching 641 million yuan. The monthly increases 5.6% annual growth of 25.2%, the new high record for a single month, the cumulative second-quarter revenue will […]
Flexible PCB or FPC is a patterned arrangement of printed circuitry and components that utilizes flexible-based material with or without flexible coverlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to the desired shape (flex) during its application. Rigid-flex PCBs […]
China plays an important role in PCB manufacturing in the world. In recent years, the global status of PCB manufacturing has tremendous change, and most PCB manufacturing has transferred to Asia, especially China. China has become the main PCB supplier of the world. In the premise that electronic products tend to be more complex, the […]
Many plating liquids are appended with additives, they will produce an analyte when the time out, it is bad for the plating, so we must be cleaned the plating tanks in a fixed cycle. If the plating surface is too light, the dispersion ability is often not so good, and it’s easy to cause the […]
