PCB FPC laser engraving machines can mark barcodes, QR codes, data matrices, text, and serial numbers on the surface of circuit boards, meeting the needs of board identification, batch management, and production history traceability. Combined with online or offline work planning, they help improve marking efficiency and reduce manual labeling and marking consumable needs in the electronics manufacturing field.

Advantages of laser marking on PCB FPC

Direct labeling reduces the need for labels and ink.

Laser-printed identification content onto PCB surfaces reduces the need for labels, inks, and ribbons required for traditional labeling and coding, simplifying marking operations and consumable management.

Non-contact processing, flexibly displaying text and barcodes.

Text, serial numbers, and QR codes can be configured in designated locations using contactless laser marking. The marking content or format can be adjusted via software to easily meet the needs of different work orders, products, and batches.

Establish board identification to support production traceability.

By using barcodes and serial numbers to link board, work order and batch information, a foundation is laid for subsequent process tracking and data retrieval, and MES/ERP system integration is optional.

Online and offline configurations allow for flexible adaptation to the production site.

Online PCB laser marking

It can connect to the front and back end equipment of the SMT production line through the interface, and incorporate board marking into the existing production process, making it suitable for manufacturing sites that require continuous operation.

Offline PCB Laser Marking Workstation

Optional automatic plate loading and unloading machines can be added to form an independent marking workstation, which can arrange operations according to the on-site flow to meet the needs of centralized marking and flexible production.

Optional features

Optional items	Application Features
CCD visual positioning	Identify the reference position of the panel and the position of the positioning mark.
Bad Mark Identification	Identify defective sub-board markings in the puzzle and skip the corresponding markings.
Bottom plate code reader	Read the existing barcode on side B, mark the associated content on side A, and establish a correspondence between the front and back data.
Mistake prevention and duplicate code prevention	Supports board orientation, component and code management requirements
MES/ERP Serial Connection	Link board identification information to work orders and production management data
Automatic board loading and unloading machine	Set up an offline marking workstation with the equipment.
Smoke purification system	Collect and process the fumes generated during the marking process to help maintain a clean working environment.

What information can a PCB laser engraving machine mark?

It can mark 1D barcodes, QR codes, data matrices, text, serial numbers and graphics for circuit board identification, batch management and production traceability.

Can PCB laser marking reduce labeling work?

Lasers can directly form identification content on suitable PCB surfaces, reducing the need for sheet-by-sheet labeling and the use of labels, inks, and ribbons for marking purposes.

Can it be used with existing SMT production lines?

It can be configured online and connected to front-end and back-end devices through the SMEMA interface; it can also be equipped with automatic board loading and unloading machines to form an offline marking workstation.

Can it be used with an MES/ERP production management system?

Optional MES/ERP connection can be added to link the marking data with production information such as work orders and batches, supporting PCB production traceability needs.
