Q&A User Guide｜Standardized Questions, Precision Answers! At JLCHub, we provide engineers with a specialized Q&A system designed to deliver faster, more targeted technical solutions. Whether you're struggling with: Design Challenges - Circuit/mechanical design bottlenecks Software Bugs - Firmware/algorithm/implementation issues Component Selection - Part compatibility/cost-performance dilemmas Process Obstacles - Production/workflow optimization Our structured Q&A format ensures you receive actionable solutions from industry experts. 1. What is the Q&A? Q&A is a problem-driven posting format focused on resolving specific technical issues (unlike general discussions). Core Features: 🎯 Structured Format: Clear titles with detailed problem descriptions 💰 Bounty System: Offer points to incentivize quality responses ✅ Solution Validation: Mark accepted answers as "Best Solution" 🔍 Smart Sorting: Answers ranked by time and community votes 2. Why use Q&A? Improves Problem Resolution Rate: Standardized question formats make problems logical and easier to understand. Centralized Q&A sections help focus community attention. Boosts Motivation to Answer: Community members earn points by providing solutions, encouraging active participation. Helps Fellow Engineers Learn and Grow: Archived Q&A exchanges become valuable resources for others facing similar issues. 3. How to Create a High-Quality Q&A Post? A well-structured question significantly increases your chances of receiving high-quality answers. Include the following details: 3.1 Precise Title: Clearly summarize your issue in one sentence (e.g., "How to resolve GPU memory overflow in TensorFlow 2.8?" instead of "Help with a technical problem"). 3.2 Detailed Context: Describe the environment (software/hardware versions, OS, etc.). Explain the steps leading to the issue (with code/commands if applicable). Attach screenshots or error logs when possible. 3.3 Expected vs. Actual Behavior: State what result you anticipated. Specify what actually occurred (with error messages, if any). 3.4 Attempted Solutions: List troubleshooting steps you've already tried (avoid "I've tried everything" statements) 3.5 Additional Resources: Include relevant documentation links or reference materials. For UI-related issues, attach annotated screenshots highlighting problem areas. 4. About Point Rewards All users can accumulate points by participating in discussions, answering questions, daily check-ins, and other activities. When creating a Q&A post, you may offer a point reward (the system suggests recommended amounts). Users whose answers are marked as “Best Answer” will receive the allocated reward points. 5. How to Access the Q&A Function You can post Q&A questions through the following methods: Click the [Ask Question] button on any category page. Select “Post as a Q&A Question” and fill in complete details. Set a point reward (adjust based on question complexity). Try the Q&A function now - don't let your questions go unanswered!

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.

To foster a professional, friendly, and technology-focused community for engineers, all users are expected to follow the rules below when creating posts or replying. 1. Maintain Clarity and Precision in Communication Use accurate wording and clear logic. For technical topics, avoid vague descriptions. For example, instead of “the circuit has an issue”, write* “after powering on, the 5V rail drops to 3.3V, likely due to the regulator overheating”*. Provide as much context as possible (e.g., chip model, tool version, waveform screenshots) to help others diagnose the issue. Use consistent terminology and standard abbreviations. For instance, MCU, PCB, FPGA, GND, VCC are acceptable. Avoid creating your own abbreviations. If you must use uncommon terminology, include an explanation to prevent misunderstanding. Maintain a neutral and objective tone. Technical discussions should be based on facts and test results, not speculation or emotion. Different opinions are welcome, but keep the conversation respectful and constructive. 2. Stay Relevant to the Category When posting, select the most appropriate category and ensure your content matches the topic. Off-topic content will be moved or removed. If unsure, post in General Discussion or contact a moderator first. Refer to the JLCHUB Community Module Guide for clarification. 3. Prohibited Content (see Community User Policy for details) The following types of content are strictly forbidden: Advertising / Promotional content Posts promoting Facebook/Whatsapp groups, online shops, or any marketing activity. Unapproved product advertisements or external service links. Spam or repeated promotional posts. Harassment / Personal attacks Mocking, insulting, or ridiculing others’ opinions or abilities. Discriminatory remarks targeting individuals, groups, or professions. Sensitive / Political topics Discussions related to politics, religion, ethnic issues, or social controversies. Content involving criminal activities, political positions, or force. False / Misleading information Deliberately spreading incorrect data, or copying projects without attribution. Passing off AI-generated or third-party work as original. 4. Enforcement and Moderation The community is maintained by both the JLC Official Team and volunteer moderators. We reserve the right, without prior notice, to: Remove or move inappropriate posts. Temporarily suspend accounts for violations. Permanently ban accounts for serious offenses. Report unlawful activity to authorities if necessary. 5. Use Q&A Posts for Faster Technical Support If your post is intended to seek solutions, consider using the Q&A format. Other users can upvote helpful answers. You can mark a reply as the “Best Answer” for community feedback. High-quality Q&A posts may be featured or highlighted. 6. Help Us Build a Healthy Community JLCHUB aims to be a long-term, stable, and professional platform for technical exchange. Every user plays a role in maintaining this ecosystem: Use the Report function to flag inappropriate content. Share your questions, feedback, or suggestions in JLCHUB.
