# Mill-Max Manufacturing Manufacturer Skill ## MPN Structure Mill-Max MPNs follow a dash-separated numeric structure: ``` [SERIES]-[FIELD1]-[FIELD2]-[FIELD3]-[FIELD4][-FIELD5][-FIELD6][-FIELD7] | | | | | | | | | +-- Additional specification fields | | | +-- Specification field | | +-- Specification field (often pin count) | +-- Specification field +-- 3-4 digit series number ``` ### Example Decoding ``` 0906-0-15-20-75-14-11-0 | | | | | | | | | | | | | | | +-- Plating option | | | | | | +-- Contact material | | | | | +-- Force specification | | | | +-- Stroke specification | | | +-- Force specification | | +-- Travel specification | +-- Type variant +-- 0906 = Spring-loaded contact series 310-93-108-41-001000 | | | | | | | | | +-- Additional options | | | +-- Row configuration | | +-- Pin count (108 pins) | +-- Profile specification +-- 310 = Header series ``` --- ## Series Families ### Spring-Loaded Contacts (Pogo Pins) | Series | Mounting | Application | Pattern | |--------|----------|-------------|---------| | 0906 | THT | Test/Programming | `^0906-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]$` | | 0907 | SMT | Test/Programming | `^0907-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]$` | | 0908 | THT | Test/Programming | `^0908-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]$` | | 0965 | SMT | Battery Contact | `^096[0-9]-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]$` | | 0985 | SMT | Board-to-Board Spring | `^098[0-9]-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]+-[0-9]$` | ### IC Sockets | Series | Mounting | Application | Pattern | |--------|----------|-------------|---------| | 110 | THT | DIP IC Socket | `^110-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 510 | SMT | PLCC Socket | `^510-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 610 | THT | PGA Socket | `^610-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | ### Board-to-Board Connectors | Series | Mounting | Application | Pattern | |--------|----------|-------------|---------| | 850 | THT | High Density B2B | `^850-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 851 | SMT | High Density B2B SMT | `^851-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 852 | THT | High Density B2B | `^852-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | ### Headers | Series | Mounting | Type | Pattern | |--------|----------|------|---------| | 300 | THT | Pin Header | `^300-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 310 | THT | Pin Header | `^310-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 311 | SMT | Pin Header | `^311-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 315 | SMT | SMT Header | `^315-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 316 | SMT | SMT Header | `^316-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | ### Receptacles | Series | Mounting | Type | Pattern | |--------|----------|------|---------| | 800 | THT | Pin Receptacle | `^800-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | | 801 | SMT | Pin Receptacle SMT | `^801-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | ### Single Row Sockets | Series | Mounting | Type | Pattern | |--------|----------|------|---------| | 350 | THT | Single Row Socket | `^350-[0-9]+-[0-9]+-[0-9]+-[0-9]+$` | --- ## Mounting Type Detection ``` THT Series: 0906, 0908, 110, 610, 850, 852, 300, 310, 800, 350 SMT Series: 0907, 0965, 0985, 510, 851, 311, 315, 316, 801 ``` Mill-Max uses the series number to indicate mounting type. This is different from most other manufacturers where mounting is encoded as a suffix. --- ## Pin Count Extraction For headers and receptacles, pin count is typically in the third field: ```java // Example: 310-93-108-41-001000 // Pin count = 108 (third field after series) String[] parts = mpn.split("-"); if (parts.length >= 3) { int pinCount = Integer.parseInt(parts[2]); } ``` --- ## Spring Pin Compatibility Spring pins are compatible replacements when: 1. Same series number (e.g., both 0906) 2. Same travel specification (group 3) 3. Same force specification (groups 4-5) 4. Same stroke specification ``` 0906-0-15-20-75-14-11-0 vs 0906-0-15-20-75-14-11-1 ^ ^ ^ ^ ^ ^ Same travel/force/stroke = Compatible (different plating) ``` --- ## Handler Implementation Notes ### Series Extraction ```java // Mill-Max series is always the first field before the dash // Example: 0906-0-15-20-75-14-11-0 -> series = "0906" int firstDash = mpn.indexOf('-'); if (firstDash > 0) { String series = mpn.substring(0, firstDash); // Validate: should be 3-4 digits if (series.matches("[0-9]{3,4}")) { return series; } } ``` ### Package Code Extraction ```java // For Mill-Max, "package code" is effectively the mounting type // Determined by series number, not a suffix String series = extractSeries(mpn); if (SERIES_MOUNTING.containsKey(series)) { return SERIES_MOUNTING.get(series); // Returns "THT" or "SMT" } ``` ### Generic Pattern Matching ```java // Mill-Max MPNs are ALL numeric with dashes // General pattern: 3-4 digit series, followed by dash-separated numbers Pattern GENERIC_PATTERN = Pattern.compile( "^([0-9]{3,4})-[0-9]+-[0-9]+-[0-9]+-[0-9]+.*$" ); ``` --- ## Component Types Mill-Max products map to these ComponentTypes: - `CONNECTOR` - All header, receptacle, B2B, spring pin products - `IC` - IC socket products (110, 510, 610 series) Note: IC sockets register under BOTH `CONNECTOR` and `IC` types. --- ## Related Files - Handler: `manufacturers/MillMaxHandler.java` - Supported types: `CONNECTOR`, `IC` - No manufacturer-specific ComponentType enum entries --- ## Learnings & Edge Cases - **Numeric-only MPNs**: Unlike most manufacturers, Mill-Max MPNs are entirely numeric with dashes. No letters. - **Series determines mounting**: The series number indicates THT vs SMT, not a suffix code. - **IC sockets are dual-typed**: 110/510/610 series register as both CONNECTOR and IC types. - **8-field spring pins**: Spring-loaded pins have the most complex structure with 8 dash-separated fields. - **Pin count location varies**: For spring pins, pin count is not directly extractable. For headers, it's the third field. - **No package code suffix**: Mill-Max does not use package code suffixes like other manufacturers. <!-- Add new learnings above this line -->
