SPI Work Instruction is a document used inSMT(Surface Mount Technology) industry, which is used to guide and standardizethe operation and maintenance of SPI(Solder Paste Inspection) equipment. SPI isa key quality control tool, which is used to detect the quality and accuracy ofsolder paste to ensure the accuracy and consistency of the welding process. SPIwork instructions usually include the following contents:

Equipment operation steps: instructoperators how to set up and use SPI equipment correctly, including opening andclosing equipment, loading PCB, setting detection parameters, etc.

Calibration and maintenance: explain thecalibration procedure of the equipment and the requirements of regularmaintenance to ensure the accuracy and reliability of the equipment.

Detection parameter setting: providesguidance on how to configure SPI equipment to meet different PCB and solderpaste requirements.

Data analysis and interpretation: explainhow to analyze the data generated by SPI to detect potential solder pasteproblems and take necessary measures to correct them.

Safety guide: includes information aboutthe safe operation of equipment to ensure the safety of operators andequipment.

SPI equipment plays a key role in SMTmanufacturing process, because the correctness and uniformity of solder pasteare very important to the reliability and performance of electronic components.The following are some positions that need to formulate SPI work instructionsin SMT industry:

Engineer: SMT engineers usually need towrite SPI work instructions to ensure the correct configuration and operationof SPI equipment, and carry out maintenance and calibration when necessary.

Operator: The operator of SPI equipmentneeds to follow the steps in SPI operation instruction to perform solder pastedetection tasks, monitor the operation of the equipment and record data.

Quality control personnel: The qualitycontrol team may need to check the data generated by SPI to ensure that thequality of solder paste meets the specifications and take corrective measureswhen there are problems.

Maintenance technicians: Maintenancepersonnel are responsible for regularly calibrating and maintaining SPIequipment to ensure its performance and accuracy. They need to follow themaintenance procedures in SPI operation instruction.

SPI work instruction is an importantdocument in SMT manufacturing, which helps to ensure the quality andconsistency of welding process, reduce the defective rate and improveproduction efficiency. Therefore, it is very important for SMT industry toformulate and follow SPI work instructions. BQC has set up professional SPI ineach position to ensure work safety and efficiency.
