DZOPTO supplies touch switches, power supplies, LED strips and demister films for smart mirrors. OEM and ODM orders are built on SMT, inspection and optical test. This page explains reflow soldering.
Cooperation models: OEM & ODM Smart Mirror Electronic Components.
Where reflow sits in the line
After solder paste printing and component placement, the board goes through reflow. Heat melts the paste and forms the joints. The board then goes to AOI and functional test.
Production uses LITUO (Shenzhen Lituo) reflow equipment for touch, power and strip-related PCBs. The oven profile is set for the board and parts on that job. It is a process setting, not a marketing spec for a finished mirror.
Which products use this step
Split touch controllers such as LTZN-03D-SX
Integrated touch + power platforms such as LTZN-01S-YT1201
Slim DC12V power boards, including the 15 mm LTZN-12V series
LED strip related control boards
Custom OEM boards built to a customer drawing
These assemblies go behind bathroom, vanity and cabinet glass. They are not finished mirrors.
What reflow is meant to control
Complete joints on the pads
No tombstoned or shifted parts after heat
A profile that can be repeated from sample to bulk lot
A cold joint or a lifted pin on a touch or power board usually shows up as a dead key, flicker or a failed incoming test at the mirror factory.
What this means for an OEM or ODM order
OEM: the stack-up and part list are yours. The reflow profile is set after the first sample board is approved.
ODM: reflow follows the current LTZN platform. A function change that keeps the same board and parts usually keeps the same profile. New heavy copper or a new package may need a new profile.
