In the manufacturing and post-processing of PCB boards, cleaning is a crucial step. However, many manufacturers face a common problem: stubborn foam generated during cleaning. This foam not only reduces the effective utilization of the cleaning tank and slows the production pace but may also lead to incomplete cleaning, leaving water marks or chemical residue on precision circuits and ultimately affecting the product's electrical performance and reliability.
To address this market pain point, Chemi Tech, with its deep technical accumulation, has developed a high-efficiency defoamer specially suited to PCB board cleaning processes. Our solution is not simple physical suppression; through unique molecular design, it achieves both rapid foam breaking and long-lasting foam inhibition. The product is highly compatible with common cleaning agents, performs stably in all kinds of water-based cleaning systems, and is easy to rinse with no residue risk.
The specific application steps are clear and simple. First, according to your cleaning tank capacity and the severity of the foam, our technical engineers help determine an economical initial addition ratio. Second, it is recommended that after the cleaning agent is added and before production begins, the defoamer be slowly added to the circulating cleaning liquid and evenly dispersed. In subsequent continuous production, only a small top-up based on the foam condition is needed to maintain a foam-free, highly efficient cleaning environment all day.
We once worked with a customer specializing in high-density interconnect board production. This customer had long been troubled by foam in the final water rinsing stage; overflowing foam made the workshop floor wet and slippery, and some boards showed slight corrosion. After adopting Chemi Tech's customized defoaming solution, the foam was effectively controlled within minutes of addition, the visibility of the cleaning tank improved greatly, and operation became safer. More importantly, board surface cleanliness was verified, and the defect rate in subsequent inspection dropped significantly, bringing the customer real quality improvement and cost savings.
Choosing Chemi Tech is not only choosing a product but also choosing a reliable process support system. We are committed to helping you clear production obstacles so that the cleaning step is no longer a weak link in the quality chain.
