In the field of electronic product processingPCBAIn productionSolder paste manufacturertheSMTSurface mount technology (SMT) processing is a relatively crucial production and processing stage.PCBAThe surface mount technology (SMT) processing is a rather meticulous entire process, and this production process often encounters some difficulties.

    SMTIn fact, a large proportion of the problems in surface mount technology (SMT) processing are caused by common printing malfunctions throughout the SMT process. Therefore, the quality of the printed matter is a crucial step in the production and processing quality.JJYSolder pasteManufacturerCommon printing faults and solutions in surface mount Technology.

    The printing method where there is no gap between the steel mesh and the circuit board is called "touch printing". It stipulates the feasibility of the structure, applicable to the precise printing of solder paste, and the consistent and flat contact between the steel mesh and the circuit board. After the printing is completed, it is separated from the circuit board, so the printing precision achieved by this method is relatively high. The key is that it is suitable for fine-pitch, fine-pitch solder paste printing.

    The solder paste can roll forward on the steel mesh under the push of the scraper.SMTThe faster speed of surface mount printing is beneficial to the resilience of the steel mesh, but it will also prevent solder paste from being missed. However, the rate is too slow, and the solder paste is not easy to roll over on the steel mesh, resulting in poor screen resolution of the solder paste printed on the solder layer. Generally, the printing rate range for fine pitch is 10 to 20 millimeters per second.

    NowadaysPCBAIn production and processing, the more common printing methods are divided into "touch printing" and "non-touch printing". The printing method with a gap between the steel mesh and the circuit board is called "non-contact printing", which is suitable for solder pastes of different viscosities.
