PTH Plated Through Hole is a hole metallization process in circuit board manufacturing, also commonly called PTH, and is an autocatalytic redox reaction. It is mainly based on the displacement reaction in chemistry to deposit a layer of copper on the pore wall as a conductive lead for subsequent copper plating. If it is conventional copper, its thickness is generally about 0.5 μm. As the most traditional copper plating preparation process, it has the following advantages and disadvantages: Advantages of PTH: ·        Copper has excellent electrical conductivity (wire inside, the conventional use of copper wire as conductive). ·        The thickness can be adjusted in a wide range, and wide adaptability (the lowest in the industry is about 0.3 μm, and the highest is up to 30 μm presently, directly replacing the subsequent copper plating process). ·        The process is mature and stable, which can be applied to all types of circuit board products (PCB/FPCB/RFPCB/metal substrate/ceramic substrate, etc.). Disadvantages of PTH: ·        Containing formaldehyde, adverse to the health of workers. ·        Large equipment investment, high production costs, and serious environmental pollution. ·        The aging control is short, and the effective time is generally 3-6 hours.

✨PCB Etching Process✨ It is a crucial step in the manufacturing of PCBs, where unwanted #copper is removed from the board to create the desired circuit pattern. The PCB board is immersed in an #etching solution (commonly ferric chloride, ammonium persulfate, or cupric chloride) which dissolves the unprotected copper, leaving behind the desired copper traces protected by the hardened photoresist. This process can vary slightly depending on the specific requirements of the #PCBdesign and the capabilities of the manufacturing facility. #PCBMay #pcbmanufacturer #pcbsupplier #pcbfactory #pcblayout #pcbassembly #electronicmanufacturing

Did you know? The products we manufacture have some very technical and intelligent functions to them. Our latest product assembly for Electroless Nickel units for coating PCBs contains a glass chamber. The glass chamber enables the chemical measurement process by firing an infrared beam through the glass chamber onto the sensor. This allows the unit to measure the parameters of the liquid in the chamber and adjust where required to meet optimum levels for chemical coating. Want to know more? #justask

Cation type ion exchange resin P-116H (Electroless plating) During the electroless Pd plating step of the PCB/FPCB plating process, P-116H can be used to adsorb Pd in water bath after the main bath. [Product Features] 1) High Pd adsorption capacity 2) Ion exchange resin in the state of precious metal cations 3) Column liquid passage method 4) GEL type: Because there are few pores, the amount of adsorption is small, but the adsorption power is strong. 5) PH range of use: PH 0 ~ 14 available [Purpose of use] P-116H is a cationic ion exchange resin, mainly used in [Pd(NH3)4]Cl2. Used for adsorption of electroless plated Pd. ※Precious metals are not adsorbed and recovered in the washing tank of each plating process. If you are using activated carbon in your final wastewater treatment, It is important to recover precious metals by using ion exchange resin for each process. It has merit, which the recovered resin can be burned and the precious metal can be sell again. For more detailed explanation Y.S.

What is blackhole in PCB process Blackhole Black holes are one of the direct electroplating technologies. Its main principle is to make the carbon powder adsorbed on the surface of the hole wall to form a conductive layer, which can be used as the conductive lead for subsequent copper plating. Usually, its thickness is 0.5~1 μm. As one of the current mainstream copper plating preparation processes, it has the following advantages and disadvantages: Advantages of Blackhole: ·        No formaldehyde, small impact on the health of workers, and small pollution to the environment. ·        The equipment investment is small, the waste treatment is simpler, and the process cost is lower than that of PTH. ·        The potion and process are relatively simple, the timeliness can reach 48 hours, and it is easier to maintain and manage. Disadvantages of Blackhole: ·        In terms of conductivity, the conductive toner is weaker than the PTH. ·        Its applicability is not as wide as that of PTH. Therefore, although it has been used on a large scale, it is mainly used for 2-layer PCB in the industry at present. High-end products such as HDI PCB are almost not used.   #PCBmanufacturing  #hdipcb  #multilayerpcb #flex-rigidpcb    #rogerspcb  #backdrill  #ENIGPCB #pcbdesign #pcbassembly
