Step Stencils for Challenging PCB Designs
SMT Stencil
Framed Stencil or Frameless Stencil
SMT Stencil
Nano-coated SMT stencils are designed to improve solder paste release, especially for fine-pitch and dense PCB designs. By applying a nano-scale coating to the stencil surface and aperture walls, the stencil becomes more hydrophobic, which helps reduce solder paste adhesion and residue during printing. 🔍 What problems can nano-coated stencils help solve? Poor paste release on fine-pitch components Inconsistent deposits on small apertures Paste sticking to the bottom of the stencil Frequent stencil cleaning during assembly ⚙️ Typical use cases Nano-coated stencils are commonly used for: Fine-pitch ICs (QFN, LQFP, small-pitch connectors) High-density PCBs Boards with mixed aperture sizes Projects requiring more stable printing consistency 🧠 Things to keep in mind Nano coating does not replace proper aperture design Paste type and printing parameters still matter It’s especially effective when combined with electropolished apertures 💬 Share your experience Have you used a nano-coated stencil before? What pitch or component type did you use it for? Did it reduce cleaning frequency or improve consistency? Hand assembly or machine printing? Feel free to start a new post to share your results, photos or questions. Your real-world experience can help others choose the right stencil for their projects.

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.

JLCHUB
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.
