Job Title: PCB Design: High-Density DMS-60 (4x15 Straight Matrix, 1.27mm Pitch) to Standard 2.54mm Breakout Board Job Description & Scope of Work: We are looking for an experienced PCB layout designer to create fabrication-ready files (Gerber package) for a custom pitch adapter breakout board. The primary objective of this board is to act as a physical bridge, adapting a high-density rectangular connector down to standard, user-friendly male pin headers for solderless prototyping. 1. High-Density Input Connector Specifications: Connector Type: LFH / DMS 60-Pin Female Socket. Physical Geometry: Straight, clean rectangular matrix. It consists of exactly 4 parallel rows, with 15 female holes per row (4x15 Grid). It is NOT a staggered or D-sub shaped connector. Pin Pitch Constraint: The pitch between pins is exactly 1.27mm (0.05 inches) both horizontally (pitch) and vertically (row spacing). 2. Standard Output Header Specifications: Connector Type: Standard Male Pin Headers. Total Pin Count: Exactly 60 pins total. Configuration: Split logically into two (2) separate single-row headers, with 30 pins each (or optimized based on fanning constraints). Pin Pitch Constraint: Must adhere strictly to the standard 2.54mm (0.1 inches) pitch, fully compatible with standard breadboard jumpers and screw terminal blocks. 3. Trace Routing & Mapping Requirements: Netlist Mapping: Straightforward 1:1 mapping from the 60 pins of the dense matrix to the 60 pins of the standard output headers. Trace Topology: Clean, parallel fanning out of the 60 traces. Avoid 90-degree trace angles; use 45-degree or smooth routing geometry to ensure neat trace distribution and clear isolation. Layer Constraint: Single-sided component placement. All components (the DMS-60 socket and the 2.54mm headers) must be mounted on the Top Layer, with routing optimized cleanly. 4. Mechanical Constraints: Board Dimensions: Must be kept as compact and efficient as possible while fully respecting standard clearance and trace widths. Mounting: Include at least two (2) M3-sized mounting holes at the corners for mechanical stabilization inside an enclosure. Required Deliverables: 1. Complete Gerber RS-274X file package (including copper, solder mask, and clear silkscreen labeling for Pin 1 and header groupings). 2. Excellon Drill files. 3. Bill of Materials (BOM) with a verified manufacturer part number for the correct 4x15, 1.27mm pitch female receptacle. 4. Pick and Place (CPL) file. 5. 3D STEP model of the finalized PCB assembly. Important Mechanical Dimension Update: Please note the exact footprint dimensions for the LFH/DMS-60 female connector mounting area (as shown highlighted in the attached image): Total Interface Width: Exactly 23.12 mm Total Interface Length (Depth): Exactly 9.2 mm The custom PCB breakout board must be designed so that the connector fits precisely within this 23.12 mm x 9.2 mm area at the input zone to ensure a perfect mechanical flush fit." Layout & Placement Constraint for the 2.54mm Headers: Positioning: Both of the 30-pin (2.54mm pitch) male headers must be strictly placed at the Top Front edge of the PCB layout. Accessibility: This placement is mandatory to ensure clear, unobstructed vertical access for plugging in female rainbow flat cable connectors from above, with no components or high-density housing blocking the wire path.

Hi I am an embedded systems engineer with over 16 years of experience in PCB layout and product-grade hardware design. I can design this high-density LFH/DMS-60 breakout board with the 4x15, 1.27mm female connector mapped 1:1 to two 30-pin 2.54mm headers at the required top front edge for clear cable access. My approach will be to first lock the exact connector footprint against the 23.12mm x 9.2mm mechanical area, then place the headers and mounting holes so the board remains compact while routing clean fan-out traces with proper clearances and 45-degree geometry. I will prepare fabrication-ready Gerbers, Excellon drill files, BOM with a verified connector part number, CPL, silkscreen labels, and a STEP model of the final assembly. I would only need the attached image/datasheet confirmation for the connector, or I can select and verify the correct part myself. Please contact me to discuss details.

I’ve read your spec for the high-density DMS breakout PCB, and this is exactly the kind of dense, signal-critical layout I handle regularly. I’ve been doing PCB design and embedded systems for over a decade, and I know that getting the routing right in a small footprint is what separates a board that works from one that needs a respin. I focus on clean trace routing, proper impedance control, and a layout that’s ready for fabrication from day one. I’ve shipped similar boards before—like a four-layer custom PCB for a BLE-enabled golf ball that had extreme size constraints and required careful antenna and power routing. That board went from schematic to verified prototype without any layout-related issues. I can apply the same discipline here, working within your dimensions and connector pinout to deliver a breakout board that performs reliably. I’m ready to review your pin assignments and layer stack up and get started immediately.

Hello, Client. I am capable of handling the PCB layout design and fabrication-ready Gerber package for this high-density DMS-60 to 2.54mm breakout board. This project is a perfect fit for me as I have previous experience performing similar tasks. I previously worked at an electronics prototyping lab where I designed multiple adapter and interface PCBs for lab instrumentation and embedded systems. One of my recent tasks involved creating a fine-pitch connector breakout board that converted a dense 1.0–1.27mm pitch header into standard 2.54mm pin headers for breadboard testing. I handled full layout in KiCad, including controlled fan-out routing, mechanical alignment with enclosure constraints, and DFM checks for fabrication readiness. I also prepared complete manufacturing packages including Gerber files, BOM with verified MPNs, CPL files, and 3D STEP exports for assembly verification. The following are a few questions I would like to clarify. ♠ Could you confirm the exact manufacturer or preferred part number (or acceptable alternatives) for the DMS-60 4x15 1.27mm connector? ♠ Are there any specific PCB thickness, copper weight, or impedance considerations required for this board? ♠ Do you have a preferred CAD format (KiCad, Altium, or EasyEDA) for the editable source files? I look forward to collaborating with you! Please send a short message here, and we will discuss the project in more detail. Thank you.

Okay, I got what you want exactly. I am a Full Stack Engineer PCB Designer with 10 years of experience, providing high-density PCB layout, Altium Designer, KiCad, multilayer routing, connector breakout design, manufacturing documentation, and DFM validation. In my opinion, the key challenge is efficiently fanning out the 4x15, 1.27mm-pitch DMS-60 connector into accessible 2.54mm headers while maintaining a compact footprint and clean routing. Careful pin mapping, trace organization, and mechanical alignment will ensure both manufacturability and ease of prototyping. This project is very similar to my previous works. I have designed numerous pitch-adapter and breakout boards for fine-pitch connectors, BGAs, and high-density interfaces requiring precise mechanical constraints and fabrication-ready outputs. My experience includes generating complete Gerber packages, BOMs, pick-and-place files, and 3D assembly models. ✅ So, I will divide your project into three major steps. 1️⃣ Create the schematic, footprint verification, pin mapping, and mechanical placement based on the 23.12mm × 9.2mm connector area. 2️⃣ Design the PCB layout with clean fanout routing, top-edge header placement, mounting holes, silkscreen labeling, and DFM checks. 3️⃣ Generate Gerbers, drill files, BOM, CPL, STEP model, and perform final validation. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project. Best regards. Maksym
