16MP USB Camera Module


USB Camera modules have been used in various different devices in our life. With the development of technology, the camera module is not untouchable in civil usage, even customized OEM Camera module is available in many manufacturers. Today we will go through the basic knowledge of the USB camera module manufacturing process.


The manufacturing process of USB Camera Module

• Current test

Connect the computer, ammeter, and module with the test cable to check whether the standby current and working current of the module is within the normal range. After opening the image and check whether the screen is normal. If there is an LED light, check whether it lights up after opening the image.


• Photosensitive component cleaning

Use 40 times “computer microscope” to check, and use a dust-free wiping cloth with a little alcohol to clean the Sensor surface. After confirming that the sensor surface is free of dirt, oil, lint, or scratches, install the cleaned lens.


• Lens focusing

In the lightbox, place the Module in the fixed fixture and aim at a certain distance of the focus chart (Chart), and start the software IQC Focus to watch the image.

Align the center of the image with the center of the sun chart and adjust the focus. At the same time, according to the black and white card, check whether the image is bad. The brightness of the light source at the center of the focus chart is between 450 Lux and 550 Lux.


• Lens dispensing

Use the dispensing bottle to place a small drop of screw on the left and right sides of the joint between Lens and Holder and the four sides of the joint between Holder and PCB. After the glue is dispensed, send the module to the drying room for 3 hours and wait for the screw fixing glue to completely solidify before proceeding to the next step.


• Copper foil

Remove the copper foil and paste it on the back of the PCB. Fold the copper foil with Mylar on the front of the PCB and fold the copper foil on the other side.


• Appearance inspection control

Product length, width, and height inspection.

Visually check that there are no foreign objects or glue in the PCB board positioning holes.

Visually verify that the position of the LABEL sticker is correct. The model number on the LABEL sticker must be the same as the model number. The LABEL sticker must not be smeared, worn, and warped, or skewed.

Do not stick, skew or lift the adhesive on the eye
