Shenzhen PCB micro corrosion dosing machine

ShenzhenCopper clad laminates require pre-treatment during chemical copper deposition, and micro etching plays a positive role as an important step in the pre-treatment process. Micro etching, also known as surface roughening, can remove the oxide layer on the surface of copper foil and use micro etching solution to etch off the copper substrate surface1um~2umCopper helps to improve the adhesion between the copper foil surface and chemical copper. However, the depth of roughening copper foil should be appropriate. Excessive roughening can lead to waste of copper and solution, and in severe cases, even expose the substrate. Insufficient roughening can reduce the adhesion between the substrate copper surface and the electroless copper plating. In order to achieve good roughening effect, it is necessary to determine an appropriate roughening rate.

●Therefore, our company mainly conducted research on the micro corrosion process that affects the copper deposition effect, developed an automatic dosing machine for testing copper content, and effectively optimized the process parameters of micro corrosion rate.

This product has been proven through extensive factory practice to have the correct content measured and tested within a certain rangeSulfuric acid, hydrogen peroxide, persulfate, organic acid or hydrochloric acid are addedAnd through the analysis of experimental results, the main factors affecting the micro corrosion rate were identified. Then, an automatic dosing machine was used to make significant changes in the impact of each factor on the micro corrosion rate. Thus improving the level of craftsmanship and quality.

●This product and a large quantityPCBFactory, medicine supplier, and horizontal equipment manufacturer collaborate together. Interested parties please call our company.

●Our company produces a micro etching copper analyzer that uses photoelectric principles to analyze changes in the concentration of etching copper solution online,Can reduce the need for manual titration testing,Applied in copper etching, it can also eliminate the need for cylinder replacement and increase production capacity.
● Built in microprocessor controlled in menu format, capable of simultaneously controlling up to4Each relay has an output terminal that can count the total flow rate or operating time of the chemical pump. Users can use the backlight sourceLCDUse the display screen to check the difference between the copper concentration displayed in grams per liter or ounces per gallon and the set point.
● Can provide stable, repeatable, and accurate concentration measurement, without being affected by aging of the plating tank, color changes, or sudden increase in sediment

●Concentration reading unit----In grams per liter(g/L)Or fluid ounces per gallon(oz/gal), backlight sourceLCDThe display screen can continuously display the current status of set points and measured values in the form of a bar chart.

The testing probe of the product needs to be selected in sections:

as0-20 g/LUse a low-level testing probe for the range

20-40 g/LThe range is the median test probe

40-80 g/LThe range is for high-level test probes

0-5 g/LTesting probes for precise positioning

●When customers choose to use it, please inform our company of the probe they choose to use to avoid unnecessary trouble.
