Function<\/mark><\/strong>
By precisely controlling the wave soldering head, selective soldering can be performed on local solder joints of the circuit board. Specific soldering areas, time and temperature can be set to meet the soldering needs of small batches and multiple varieties of circuit boards.<\/p>\n\n\n\n

Advantages<\/mark><\/strong><\/p>\n\n\n\n

Efficient and flexible:<\/strong><\/p>\n\n\n\n

Replaces traditional whole-board soldering, reduces solder waste and secondary processing, and is suitable for sample development, small-batch production or rework scenarios.<\/p>\n\n\n\n


Precise temperature control:<\/strong><\/p>\n\n\n\n

Avoids damage to sensitive components caused by high temperature of the whole board, improves soldering yield and component reliability.<\/p>\n\n\n\n


Easy to operate:<\/strong><\/p>\n\n\n\n

Desktop-level equipment takes up little space, and the program settings are intuitive, reducing labor costs and technical barriers.<\/p>\n\n\n
