AF motor WBT01 for Low antenna interference cameraMP

function:
autofocus
pixels:
8M
Compared with the old products, what are the improvements(Structure, material, technology, process, performance and use function)
With the increasing mobile phone camera pixel camera, auto focus motor dynamic axis tilt angle requirements increasingly strict, consider upgrading the camera autofocus motor can meet the high pixel application, the new products of high pixel camera autofocus motor has the following improvement:
  Old products new product utility
material quality Metal case Non-metal case To reduce the interference caused by the motor magnet coil to the antenna signal
structure To achieve case impact strength by metal material To achieve case impact strength by structure upgrading Having passed through mechanical reliability tests such as drop, roller, mechanical impact and short distance drop
design The motor magnet coils being evenly arranged on the four sides and four corners of the motor. 1/3 area of the motor being free of magnet coil for the special design of the motor magnet coil To reduce the interference caused by the motor magnet coil to the antenna signal
Technology Single-sided unipolar magnetic polarization Single-sided multipolar magnetic polarization To narrow coil-covered area to reduce the interference caused by the motor magnet coil to the antenna signal
performance ordinary linearity: 10um~15um 10um~15um: ≤5μm Fast and precise focus
Use function Easily interfered antenna signals due to closely arrangement Reduced antenna signal interference for upgraded antenna arrangement Contributing to narrow the top border of the phone, maintain communication quality and clear front camera focus
