manufacturing producedure

Step1 Solder paste printing

PWB solder paste printing ,to ensure that the volume of solder paste of each solder joint meets the standard, and then flows into the next process SMD process

STEP 2 SMT line

The circuit board installs the SMD components (Chip parts + IC parts) and the Mount Connecter to the specified position of the circuit board components through the surface mount equipment and flows into the next process

Step3 AO inspection

Use AO optical inspection equipment to check whether the installed components of the circuit board are wrong, missing, and misaligned; select and deal with the poorly installed circuit boards. Test qualified products flow into the next process

Step4 IC Testing

The circuit board flows into the special reflow equipment, and the circuit board and the SMD components are welded and fixed by soldering

Step5 Reflow soldering

Use ICT test equipment to detect whether the semi-finished PCBA components that have been soldered have soldering, short circuits, wrong parts, few parts, and internal abnormalities of the circuit board. Send the qualified PCBA to the next process

Step6 DIP line

Non-SMD components need to be manually inserted into the mounting holes of the circuit board, and the manually installed circuit board should be placed in the wave soldering fixture for mounting

Step7 Solder line

The circuit board flows into the special wave soldering equipment to weld the circuit board and the pins protruding from the plug-in device

Step8 Ket materials functional Test

Before the semi-finished product is assembled, the performance of several key components such as circuit board, battery and air pump is tested by special instruments; qualified products flow into the semi-finished product assembly process

Step9 Semi-finished product Assemble

Install the circuit board, battery, and air pump on the plastic case, and test whether the button is normally turned on and off, whether the LED light is normal, and whether the long press can work normally

Step10 Semi-finished aging

Aging test the assembled semi-finished product and charge it for more than 3 hours to ensure that the battery is fully charged; check whether the buttons, LED lights, and charging are normal. Defective products are sent for repair, and qualified products flow into the next process

Step11 Finished product assembly

Assemble the semi-finished product that has passed the aging test and is fully charged on the casing, and check that the appearance of the casing is flawless and the position of the USB charging port is accurate.

Step12 Finished product Aging

Aging test the assembled product and charge it for more than 3 hours to ensure that the battery is fully charged; check whether the buttons, LED lights, and charging are normal. Each test is qualified and sent to the preparation and packaging process
