What is DPM

DPM is the English abbreviation of Direct Part Mark (Direct Part Mark). DPM represents a printing technology. DPM can also be called  direct product marking.

It is used to mark parts in the mechanical and electronic industry using laser dot etching and other methods, mostly with QR codes. The most commonly used type of barcode is the dataMatrix QR code.

Direct Part Mark Main Applications:

The DPM code is a fixed part of the product and can be identified throughout the product's life cycle. When the parts are in adverse or harsh environmental conditions and other identification methods cannot be used, "direct part marking" can achieve permanent part tracking.This achieves the purpose of reducing downtime, overhead and costs while improving the efficiency of the enterprise.

This kind of datamatrix codes are used in a variety of industries, including aerospace, component marking, food and beverage, pharmaceutical, defence, mail and print media, as these organizations often run complex operations where tracking and traceability are critical.

DPM codes Advantage:

The dataMatrix QR code has large coding capacity, high density, and high information security. The minimum size is the smallest among the left and right code systems. Therefore, the dataMatrix 2D barcode has become the most commonly used barcode type for DPM codes.

Data Matrix 2D barcode also has the following characteristics:

1. The encodeable character set includes all ASCII characters and extended ASCII characters, a total of 256 characters.

2. Barcode size (excluding blank area): 10×10 ~ 144×144

3. Data capacity: 2235 alphanumeric data, 1556 8-bit data, 3116 digital data.

4. Error correction: Use the Reed-Solomon algorithm to generate polynomial calculations to obtain error correction codes. Different sizes should use different numbers of error correction codes.

Shortcoming:

Although it can store a large number of characters, far more than most 1D barcodes, Data Matrix codes still have an overall character limit and cannot be read with traditional 1D barcode scanners.

A professional DPM code reader is required to read.
