Standard manufacturer reflow ovens require a major cleaning once a month to ensure product quality and stable equipment performance parameters. This involves removing detachable components such as condensers, fans, and filters for cleaning. For wave soldering, filters and chain claws need to be cleaned regularly to remove resin stains and high-temperature carbonization. This prevents resin and solid chemical residues from adhering to the furnace cavity, which could adversely affect the performance parameters and operating conditions required for product production in the reflow oven.
In SMT reflow and DIP wave soldering processes, as well as tunnel ovens used for drying and curing resin materials through heating methods, resin residues and solid chemical residues may accumulate on the furnace cavity over time due to operating cycles. Prolonged exposure to high temperatures can lead to carbonization, forming stubborn stains. These residues pose a risk to the performance parameters and operating conditions required for product production in the reflow oven. Generally, to ensure product quality and stable equipment performance parameters, standard manufacturer reflow ovens require a major cleaning once a month and a quick cleaning every two weeks.
Traditionally, solvent-based products are used for cleaning SMT fixture and reflow oven cavities. These products are applied by brushing, spraying, or coating the cavity surfaces, and then wiped or brushed to remove and dissolve stains. Multiple cleaning cycles with spraying of cleaning agents are usually required to ensure thorough removal of stains. However, due to the uneven application and flow of liquid cleaning agents during brushing and spraying, it is difficult to maintain sufficient soaking and reaction time between the cleaning agent and stains. This often results in suboptimal cleaning effectiveness. Many manufacturers have now switched to using Silman Tech fixture cleaning machines, which are convenient, efficient, and time-saving. This concludes the description of the SMT fixture and reflow oven cleaning method, hoping it will be helpful to you.
