Whether there are so many days and nights, we are all worried about the abnormal situation of circuit board processing. Everyone who is worried about the delivery of the board has a customer behind me. Let us come today. Analyze how to deal with abnormal PCB circuit board processing, solve problems for customers, and worry for you and me.
During the processing of the circuit board, it is inevitable that there will be several defective products, which may be caused by machine errors, or may be caused by human factors. If the hole breaking state is a point distribution rather than a complete circle breaking phenomenon, it is called a point shape. The hole is broken, and some people call it "wedge hole breaking". Common causes arise from poor processing of the desmear process. When the PCB circuit board is processed, the desmear process is first treated with a leavening agent, followed by a strong oxidizing agent "permanganate", which removes the dross and creates a microporous structure. The oxidant remaining after the removal process is removed by a reducing agent, and the typical formulation is treated with an acidic liquid.
Since the residue is not seen again after the treatment of the slag, the monitoring of the reducing acid is often neglected, which may leave the oxidant on the wall of the hole. After the board enters the chemical copper process, the board will be micro-etched after the pore treatment, and the residual oxidant is again soaked by acid to peel off the resin in the residual oxidant zone, which is also equivalent to destroying the pore former.
I don't know if you have any understanding of these abnormalities in the processing of circuit boards. Our customers are always worried about scrapping the board. If there is a problem, we must first analyze the problem and then solve the problem. Is the delivery time slow? What causes the delivery time to be slow? What are the abnormalities in the processing of PCB boards? This is what every one of our operators and our dear customers need to know.
Of course, every step in the PCB circuit board processing process requires us to strictly control, because the chemical reaction sometimes happens slowly in the corner we are not paying attention to, thus destroying the entire circuit. Everyone is wary of this kind of hole breaking state.
When our board personnel understand the abnormalities that will occur in the processing of circuit boards, we will be more cautious in every process of circuit board processing, and our customers understand these, after the circuit board processing It will be more cautious, not just processing, but processing for quality.
Circuit board processing is no longer abnormal, Shenzhen Huihe Circuit focuses on circuit board proofing circuit board processing, industry 10 years of experience, high-precision circuit board manufacturers, industry leading position.
