JLCHub Category System Overview & Posting Guide

To improve the efficiency of technical discussions and the accuracy of content search, JLCHub organizes all posts by category. This guide explains the principles behind the category system and gives suggestions on how to use it effectively.

1. Category Structure: JLC-Specific vs. General Engineering

JLCHub categories are divided into two main groups:

1.1 JLC Global (JLC-specific content)

Covers topics directly related to JLC services, including:

• Platform Services and Updates (announcements, events, new feature releases)
• Order & Technical Support (e.g., SMT assembly, prototyping rules, component sourcing process)
• Customer Communication & Feedback (e.g., bug reports, feature requests, shipping experiences sharing)

This section helps users quickly access official information and engage with JLC more efficiently.

1.2 Engineering & Technical (General technical content)

Focus on technical issues in engineers' daily design, debugging, and learning, including:

• Hardware: electronics, mechanical hardware, and related subjects
• Software: embedded system development and hardware-related software (with future plans to include pure IT topics)
• Engineering Theory (planned): fundamental engineering theories and principles

Such content is categorized by specialized technical fields, aiming to help engineers from different disciplines quickly locate relevant topics and engage with corresponding professional circles.

2. Dynamic Adjustment of Subcategories

To continuously optimize our categorization system, we regularly evaluate the following two dimensions:

• Domain Accuracy: Does the category clearly represent a specific knowledge area? (e.g., “Control Engineering” is clearer than “Automation”).
• Content Volume: Is there enough activity and user interest to justify a standalone category?

Adjustment Principles:

• If posts on a certain topic grow rapidly, moderators may create a dedicated category.
• Niche or overlapping categories may be merged or hidden.
• Category names will aim to remain professional, standardized, and unambiguous.

Suggesting New or Updated Categories

Any user can post suggestions in the JLCHub section (recommended format: Proposed category name + Reason for suggestion + Example topics).

3. Always Choose the Most Relevant Category When Posting

Picking the right category makes your post easier to find and more likely to get quality replies.

👉 Correct category = faster responses + better visibility in recommendations.

4. Official Team Assists with Category Optimization

The JLC official team and volunteer moderators will regularly review posts and help maintain the system by:

• Moving posts that are clearly miscategorized
• Reassigning posts that were left uncategorized or in the default category
• Contacting authors with suggestions for better category choices

We encourage all users to take a few extra seconds to choose the right category when posting. This reduces unnecessary moderation and ensures your content reaches the right audience immediately.
