Ferric chloride, a reusable etchant that is safe to use, is used to etch the majority of metals. It is possible to regenerate and reuse ferric chloride. For specialty metals and alloys, other proprietary etchants, such as nitric acid, are employed.
Regardless of the surface design, stainless steel may be etched using a unique electro-chemical technique called micro-etching to provide a consistent smooth finish. Areas that are normally unreachable can be etched with this adaptable finish.
The inner layers of a rigid PCB are typically removed using the acidic approach. Either cupric chloride or ferric chloride is employed in this method. The more popular of the two solutions, cupric chloride, precisely removes tiny features while offering a steady etch rate and continual regeneration.
The Global Microetching chemicals market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Atotech announces the launch of ST- Line.the introduction of ST-Line, cutting-edge machinery created to meet the needs of PCB manufacturing processes for solder mask and dry film pretreatment.
The new line, which is completely compatible with Atotech’s current CupraEtch pretreatment chemical product line, is anticipated to increase yields and lower manufacturing costs.
Atotech manufactures this equipment at its new facility in Guangzhou using its high quality and high precision production capabilities.
The business believes that now is the perfect moment to launch ST-Line in conjunction with CupraEtch chemical solutions because of the quick adoption of finer lines and spacing across PCB applications.
A versatile microetch solution for the pretreatment and adhesion promotion of principal imaging resists and soldermasks is created when ST-Line and Atotech’s CupraEtch product line are combined.
Customers may use the machine for MLB, HDI, and Package substrate applications for inner and outer layer photoresist pretreatment as well as solder mask pretreatment (compatible with all Final finishes, including ENIG and IMT).
The line is of superior quality and design and complies with strict safety requirements. The simplicity of use, clear safety controls, and completely regulated temperature sensing in the dryer module are some of the line’s standout features.
