Code Marking and Vision Inspection for Electronics
Mark QR codes, Data Matrix codes, serial numbers and text on PCBs, plastics and polymers, with in-line inspection of presence, position and readability.
The short answer
Electronic components need small, durable codes that read reliably. A 355 nm UV laser is an ink-free option for many materials and should be tested together with a code reader or vision camera.
What to consider
These details help match the printer, ink, printhead, laser and inspection equipment to your application.
Code dimensions
Small areas require a cell size and spacing that the reader can reliably decode.
Material and surface
PCBs, plastics and polymers produce different mark contrast and clarity. Test actual materials.
Inspecting every item
Coordinate the camera, lighting and trigger timing with product speed and position.
Technologies to test
Laser marking and machine vision for small codes must be assessed against the material, mounting position and actual environment.
Marking PCBs, plastics and polymers
Test the F7100U 5W or 10W model on actual materials
Test actual samples before choosingRead QR codes, Data Matrix and barcodes
Define code size, reading distance and speed
Test actual samples before choosingInspect position, presence and product characteristics
Design lighting, lenses and pass/fail criteria
Test actual samples before choosingConnect inspection results to rejection
Define signals, product tracking and safety
Test actual samples before choosingTest under realistic production conditions
Good samples cover the actual materials, colours, messages and speeds, revealing limitations before investment.
Frequently asked questions
Practical answers to help you prepare for a discussion with our engineers.
Can a QR code be marked on a PCB?
Yes, when laser power, code size and parameters suit the PCB surface. Test actual marking and reading before defining the specification.
How does a vision camera differ from a code reader?
A code reader focuses on decoding barcodes and 2D codes. A vision camera inspects appearance, position or presence and may also read codes depending on the model and system design.
What information is needed to start a project?
Send product samples, code dimensions, material, speed, marking position and inspection requirements to select a suitable laser, camera, lens and lighting.
Choosing a system with Better Code
Send your sample
Specify the material, message, position and line speed.
Test and compare
Assess clarity, adhesion, readability and limitations.
Installation and support
Select equipment, install, train operators and plan maintenance.
Let Better Code assess your samples
Send product photos, material details, print data and production speed so we can select and test the right technology.
