Why Choose TONFUL Pin Header
Premium High-Temp Insulators
For SMT and reflow soldering processes, we utilize advanced high-temperature plastics such as LCP, PA6T, and PA9T. This ensures the pin header insulators maintain their structural integrity and withstand temperatures up to 260°C without melting or blistering.
Precision Contact Plating
Reliable conductivity is critical. We offer robust plating options including Gold Flash, Selective Gold, and Matte/Bright Tin over a nickel underplate. This multi-layer plating process prevents oxidation, reduces contact resistance, and guarantees a long mating lifecycle.
Extensive OEM Customization
Don't settle for off-the-shelf compromises. We provide flexible customization for pin lengths (mating/solder sides), insulator heights, specific bend angles (for right-angle headers), and missing pins to perfectly match your PCB layout.
Strict Coplanarity & Quality Control
For Surface Mount (SMT) headers, flat alignment is everything. Our automated assembly lines feature integrated Automated Optical Inspection (AOI) to ensure strict coplanarity tolerances (typically ≤0.10mm), guaranteeing defect-free automated pick-and-place assembly for our clients.
Factory-Direct Pricing & Scalability
By eliminating the middleman, Tonful Electric provides highly competitive wholesale pricing. With our fully automated pin-insertion machines, we possess the manufacturing capacity to support both low-volume prototyping and high-volume mass production with consistent quality.
Fast Lead Times & Reliable Supply
We understand that production delays are costly. Thanks to our streamlined manufacturing processes and extensive raw material inventory, we consistently deliver fast turnaround times for both standard metric pitches (1.0mm, 2.0mm) and imperial pitches (1.27mm, 2.54mm).
Professional Selection Guide
Step 1: Determine the Pitch Size
The most critical dimension is the pitch (the center-to-center distance between pins). Industry-standard options include 1.0mm, 1.27mm (0.05"), 2.0mm, and 2.54mm (0.1"). Your choice must perfectly match the footprint of your PCB layout and the mating female receptacle.
Step 2: Choose the Mounting Orientation
Select how the header will attach to the printed circuit board. Options include Straight (180°) or Right-Angle (90°) for Through-Hole Technology (THT / DIP), and Surface Mount Technology (SMT / SMD) for automated high-density board assemblies.
Step 3: Specify Rows and Pin Count
Pin headers are available in Single Row, Dual Row, Triple Row, or Quad Row configurations. Calculate the total number of circuits (contacts) required for your power or signal transmission. We can manufacture or pre-cut the headers to your exact required pin count (e.g., 2x10 pins).
Step 4: Define Pin Lengths and Insulator Height
To ensure a secure and flush connection, standard dimensions might not always work. You must specify the mating length (the upper part that plugs into the female header), the solder tail length (which must accommodate your specific PCB thickness), and the custom plastic insulator height.
Step 5: Select the Optimal Contact Plating
Choose the contact finish based on your application's reliability and cost requirements. Gold flash or selective gold plating is ideal for high-cycle signal applications requiring low contact resistance and anti-corrosion. Matte or bright tin plating is a highly cost-effective solution for static power connections.
Step 6: Match the Insulator Material to Your Process
Your PCB assembly method dictates the plastic required. For standard wave soldering, PBT is sufficient and cost-effective. However, if your PCB goes through high-temperature SMT reflow soldering ovens, you must specify high-temp plastics like LCP, PA6T, or PA9T to prevent the insulator from melting or deforming.

Frequently Asked Questions
We have compiled some common questions from our clients. If your question isn’t included here, our customer service is always available to help. We’d love to talk with you.
Q1: Can Tonful customize the pin length and insulator height for our specific PCB?
Yes, absolutely. Customization is our specialty. We can modify the mating pin length, solder tail length, and the plastic insulator height to perfectly match your PCB thickness and mating requirements. Contact our engineering team with your dimensional drawings for a fast review.
Q2: What is the Minimum Order Quantity (MOQ) for custom pin headers?
For standard sizes (like 2.54mm or 2.0mm pitch with standard lengths), we have a very low MOQ. For highly customized dimensions (non-standard pin lengths, missing pins, or specific gold plating thickness), the MOQ is typically evaluated based on production efficiency. We always support prototype runs before mass production.
Q3: What packaging options do you offer for automated assembly (SMT)?
For standard through-hole (DIP) headers, we typically use secure PE bags or tray packaging. For Surface Mount Technology (SMT) headers intended for automated pick-and-place machines, we strongly recommend and provide Tape and Reel (T&R) packaging with or without a pick-up cap/film to ensure maximum manufacturing efficiency.
Q4: Will your pin header insulators melt during the reflow soldering process?
Not if the correct material is selected. Standard PBT plastic is suitable for wave soldering but will deform in a reflow oven. For high-temperature SMT reflow processes (often reaching 260°C for lead-free solder), you must specify high-temp insulators such as LCP, PA6T, or PA9T. Please inform us of your soldering method when requesting a quote.
Q5: What is the difference between Gold Flash and Selective Gold plating?
Gold Flash applies a very thin layer of gold over the entire contact, providing basic corrosion resistance and good conductivity for general applications. Selective Gold applies a thicker, specified layer of gold (e.g., 3μ”, 15μ”, 30μ”) only on the critical mating area, while the solder tail is usually tin-plated. This ensures high durability for frequent plugging/unplugging while keeping costs optimized.
