Depending on the method of connecting the circuit boards, board-to-board connectors are classified into various types, each with its own characteristics.<\/p>\n<ul>\n<li><strong>Pin-row connectors<\/strong>: These are a type of low-cost connector with a wide pitch. More compact options include compact header connectors and thickened header connectors. The choice of board-to-board connector type depends on the specific application requirements.<\/li>\n<li><strong>FPC\/FFC Connectors<\/strong>: For modern smart hardware devices, FPC connectors are the preferred choice. FPC connectors offer flexibility, a compact size, and a variety of shapes, allowing them to perform exceptionally well in space-constrained applications. FFC connectors, on the other hand, excel in high-density interconnects and high-speed serial applications.<\/li>\n<\/ul>\n<h2>Advanced: Six Key Parameters for Connector Selection<\/h2>\n<ol>\n<li><strong>Pitch<\/strong>: The center-to-center distance between adjacent contacts determines the minimum size a connector can achieve; common values range from 0.3 mm to 2.54 mm;<\/li>\n<li><strong>Stacking Height<\/strong>: The total height of the board-to-board connector assembly is a hard constraint in the structural design and must be confirmed first;<\/li>\n<li><strong>Number of insertions and removals<\/strong>: Consumer products typically require dozens of cycles, while industrial and test equipment may require several hundred or more;<\/li>\n<li><strong>Rated Current<\/strong>: The current-carrying capacity of each contact; for power connectors, calculations must be based on worst-case conditions;<\/li>\n<li><strong>Contact Resistance and Insulation Resistance<\/strong>: The former affects voltage drop and heat generation, while the latter relates to insulation safety;<\/li>\n<li><strong>Operating Temperature and Environmental Class<\/strong>: In environments with high temperatures, high humidity, or vibration, select products with the appropriate specifications.<\/li>\n<\/ol>\n<p>Article 2 is the one that most often causes problems.<strong>Miscalculating the stacking height is the most common cause of rework.<\/strong>: When selecting a part, we only considered the height of a single connector, ignoring the actual total height after assembly as well as the cumulative effect of tolerances. The correct approach is to refer to the specifications provided by both manufacturers, take the maximum assembly height, and add the tolerance.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"963\" height=\"542\" class=\"alignnone size-large wp-image-8456\" src=\"https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/08\/manufacturing-of-double-sided-fpc-soft-board.jpg\" alt=\"Manufacturing and Connection Technologies for Double-Sided FPCs\" srcset=\"https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/08\/manufacturing-of-double-sided-fpc-soft-board.jpg 963w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/08\/manufacturing-of-double-sided-fpc-soft-board-300x169.jpg 300w, https:\/\/www.jingpengpcb.com\/wp-content\/uploads\/2023\/08\/manufacturing-of-double-sided-fpc-soft-board-768x432.jpg 768w\" sizes=\"auto, (max-width: 963px) 100vw, 963px\" \/><\/p>\n<p>For high-speed routing rules, see<a href=\"\/en\/blog\/nine-high-speed-pcb-signal-routing-rules\/\">Nine Rules for High-Speed PCB Signal Tracing<\/a>; For signal integrity, see<a href=\"\/en\/blog\/pcb-design-signal-integrity\/\">Signal Integrity Issues in PCB Design<\/a>\u3002<\/p>\n<h2>Backplane Connectors: Ensuring High-Speed Data Transmission<\/h2>\n<p>Backplane connectors link individual boards to the backplane and transmit high-speed differential signals, single-ended signals, or high currents. These connectors must strike a balance between high-speed performance and high density. Backplane connectors serve as \u201chigh-speed bridges\u201d for high-end equipment such as data center storage devices and servers, ensuring their proper operation.<\/p>\n<p>Currently, there are key milestones in high-speed data transmission for backplane connectors, including 28 Gbps, 56 Gbps, and 112 Gbps. Speeds of 56 Gbps and above are referred to as high-speed backplane interconnects. At the 56 Gbps level, some domestic and international manufacturers have already achieved a balance between high speed and high density; however, when it comes to speeds exceeding 56 Gbps, only a few established international manufacturers have so far achieved this balance of high speed and high density at 112 Gbps.<\/p>\n<h2>Advanced: What Specifications Should You Look for in High-Speed Connectors?<\/h2>\n<p>Once data rates reach the Gbps range, connectors are no longer merely \u201cconductive metal plates,\u201d but rather an integral part of the transmission link.

These connectors are a subcategory of board-to-board connectors, and their primary use is to expand the functionality of computers or other electronic devices by inserting module cards and expansion cards. These cards establish an electrical connection by plugging into edge connectors on the host circuit board.<\/p>\n<p>Classic applications include PCI expansion cards, which are used to provide computers with greater system expandability and higher bandwidth. These connectors must be designed in accordance with the PCI-SIG PCIe CEM specification to achieve higher connection performance, particularly in terms of high-speed data transfer. Today, some manufacturers have already achieved support for data rates of 32 GT\/s on fifth-generation PCIe Gen CEM connectors.<\/p>\n<p>Another typical application is the M.2 connector, which has replaced the mSATA interface standard. This edge-mounted connector has significant demands for high-speed performance, and its optimized contact design enhances high-speed capabilities. In addition, the M.2 connector is smaller in size and volume, providing more space for PCB design.<\/p>\n<h2>Advanced: Connector Pad Design and Assembly Considerations<\/h2>\n<ul>\n<li><strong>Pad dimensions strictly in accordance with the specifications<\/strong>: Connector pads have tight dimensional tolerances, and making modifications on your own can easily lead to soldering defects or misalignment;<\/li>\n<li><strong>Pay attention to the positioning posts and mounting feet<\/strong>: The positional accuracy of mechanical mounting holes is just as important as that of the solder pads;<\/li>\n<li><strong>Support for Insertion and Extraction Forces<\/strong>: Force is transmitted to the solder joints during insertion and removal; add a retaining structure or underfill as needed;<\/li>\n<li><strong>Allow room for maneuver<\/strong>: Allow space above the flip-top connector for the latch to open;<\/li>\n<li><strong>Be Aware of No-Fly Zones<\/strong>: Avoid routing traces and vias beneath the connector housing to prevent short circuits and interference.<\/li>\n<\/ul>\n<p>Clause 3 is particularly important for fine-pitch connectors.

How do you choose board-to-board connectors and pin headers?<\/h3>\n<p>Consider pitch, height, and reliability requirements. Pin headers are low-cost, easy to solder by hand, and simple to debug; they are suitable for applications with wider pitch, where height is not a critical factor, and frequent assembly and disassembly are required. Board-to-board connectors are compact, high-density, and provide a secure fit; they are suitable for products with limited space. Board-to-board connectors are commonly used in mass-produced products, while pin headers are often retained during the development phase.<\/p>\n<h3>2. What is the difference between FPC connectors and FFC connectors?<\/h3>\n<p>FPC connectors are used to connect flexible printed circuits (FPCs), which are etched-formed flexible circuits that can be made very thin and incorporate components; FFC connectors are used to connect flat flexible cables (FFCs), which are flexible cables consisting of parallel conductors. FFCs are less expensive and are suitable for simple parallel interconnections. The appropriate connector must be selected based on the type of cable; the two are not interchangeable.<\/p>\n<h3>3. Is a smaller connector pitch always better?<\/h3>\n<p>No. The smaller the pitch, the higher the requirements for PCB pad accuracy, placement accuracy, and the manufacturing precision of the connector itself\u2014and both costs and defect rates rise accordingly. You should select the maximum pitch that meets your requirements based on the actual number of pins and space constraints, rather than simply aiming for the smallest possible pitch.<\/p>\n<h3>4. Will high-speed signals inevitably degrade when passing through a connector?<\/h3>\n<p>There will certainly be an impact, but it is manageable. Connectors introduce insertion loss, reflection, and crosstalk; the key is to factor these into the link budget and select products that are compatible with the data rate. At the same time, pay attention to the fan-out of the connector\u2019s pin area and the handling of the reference plane, as the design of these elements often has a greater impact than the connector itself.<\/p>\n<h3>5. How do you choose the plating for connectors?<\/h3>\n<p>They are typically gold-plated or tin-plated. Gold-plated contacts offer high reliability and corrosion resistance, making them suitable for low-voltage, small-signal applications and frequent insertion and removal; tin-plated contacts are low-cost and suitable for applications with infrequent insertion and removal and favorable environmental conditions. When selecting contacts, a comprehensive assessment should be made based on the number of insertion and removal cycles, signal levels, and the operating environment.<\/p>\n<h3>6. Are gold fingers considered connectors?<\/h3>\n<p>This refers to one side of an edge-to-edge connection. Gold fingers are gold-plated contacts on the edge of a PCB that mate with a slot to form an edge-to-edge connection. They do not require a separate connector component, but they have strict requirements regarding plating thickness, chamfers, and dimensional tolerances, and must be designed in accordance with specifications.<\/p>\n<h3>7. Why are there specifications for the number of insertion and removal cycles for connectors?<\/h3>\n<p>Because each insertion and removal cycle wears down the contact plating, contact resistance increases accordingly. Once the rated number of cycles is exceeded, contact reliability can no longer be guaranteed. For applications requiring frequent insertion and removal, models with a high insertion\/removal cycle life should be selected, or the design should be modified to use soldered connections.<\/p>\n<h3>8. What should be considered when designing connector pads?<\/h3>\n<p>The primary principle is to design the pads according to the specifications in the datasheet; do not make adjustments on your own. Additionally, pay attention to the positional accuracy of the alignment holes and mounting pins, the configuration of no-place zones, and the mechanical support for insertion and removal forces. Pad misalignment can cause placement errors and soldering defects, and is a common source of problems in mass production.<\/p>\n<p><strong>Related Recommendations<\/strong>\uff1a<a href=\"\/en\/blog\/production-process-of-halogen-free-pcb\/\">Manufacturing Process for Halogen-Free PCBs<\/a> \u00b7 <a href=\"\/en\/blog\/pcb-design-signal-integrity\/\">Signal Integrity Issues in PCB Design<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>PCB\u8fde\u63a5\u5668\uff0c\u4e5f\u88ab\u79f0\u4e3a\u5370\u5237\u7ebf\u8def\u677f\u8fde\u63a5\u5668\uff0c\u662f\u4e13\u4e3a\u8fde\u63a5\u548c\u56fa\u5b9a\u5370\u5237\u7ebf\u8def\u677f\u800c\u8bbe\u8ba1\u7684\u5173\u952e\u7ec4\u4ef6\u3002\u5728\u7535\u5b50\u5de5\u4e1a\u4e2d\uff0cPCB\u8fde\u63a5\u5668 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"slim_seo":{"title":"What Are the Types of Board-to-Board Connectors?
