SMT Placement for LED Mirror Touch and Power Boards | DZOPTO
The step after solder paste printing on OEM and ODM mirror electronics.
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 component placement.
Cooperation models: OEM & ODM Smart Mirror Electronic Components.
Where placement sits in the line
After solder paste printing, parts are picked and placed on the pads, then the board goes to reflow, AOI and functional test.
Production uses JUKI pick-and-place equipment for the small packages on compact mirror boards. Placement accuracy in this process is in the 0.02–0.04 mm range. That figure describes the machine step. It is not a product specification 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 assemblies
Custom OEM boards built to a customer drawing
These assemblies go behind bathroom, vanity and cabinet glass. They are not finished mirrors.
What placement is meant to control
Part on the correct pad
Polarity and orientation
Repeatable position from sample to bulk lot
Touch, power and lighting boards for mirrors are compact. A shifted part shows up later as a dead key, a noisy supply or a failed test.
What this means for an OEM or ODM order
OEM: the bill of materials and footprint are yours. Placement follows the approved gerber and coordinate file.
ODM: placement follows the current LTZN platform. A function change that stays on the same outline usually keeps the same program. A new outline needs a new placement file.
