In the PCB manufacturing process, foam generated by chemical bath systems is a common problem affecting product yield and production efficiency. Foam not only causes quality problems such as incomplete development, plating voids and surface defects, but also causes chemical liquid overflow, reduced equipment utilization, and even increased raw material loss and environmental pressure. How to control foam stably and efficiently has become a bottleneck that many PCB manufacturers urgently need to break through.
Relying on its in-depth understanding of PCB processes, Chemi Tech has developed a series of highly targeted dedicated defoamers. The core of our product design is the balance between rapid defoaming and lasting foam suppression, and it can maintain excellent performance under harsh conditions such as strong acids, strong alkalis, high temperatures and mechanical shear. Its characteristics of low dosage and high compatibility ensure that while eliminating foam, it does not adversely affect the function of the chemical liquid itself or subsequent processes.
In response to the defoaming needs of PCB production, we provide clear solution steps. First, carry out on-site diagnosis of the foam problem, analyzing the foaming stage and the chemical bath system. Second, recommend a matching defoamer model according to the specific process (such as inner-layer treatment, plating, development and film removal). Then, provide detailed dosage recommendations and dosing method guidance to ensure smooth introduction into the production line. Finally, we provide follow-up service and optimize the usage plan to achieve a long-term stable defoaming effect.
We once assisted a customer focusing on the production of high-density interconnect boards in solving its stubborn foam problem in the copper plating stage. The customer's production line frequently suffered from uneven plating due to foam. By introducing our customized defoamer solution, while maintaining the original performance of the chemical liquid, the foam was immediately controlled, the integrity of the plating inside the holes was significantly improved, and the product defect rate was effectively reduced. The customer gave positive feedback on the stability of the final effect.
Choosing Chemi Tech means choosing not only a defoamer, but also a partner dedicated to improving the stability of your process. Our technical team is committed to using professional products and technical services to help you overcome foam obstacles and achieve more efficient and higher-quality PCB production.
