PCB Fabrication Capabilities
Modern electronics need advanced PCB Fabrication. LT CIRCUIT meets these needs with top materials and careful work. They use strong quality checks. The company helps many types of projects. These include high-density interconnects and special finishes. They also offer testing services.
Advanced Materials
LT CIRCUIT picks materials that follow strict rules. They use substrates like FR-4, Rogers RO4350B, and RO4003C. These materials have low dielectric loss. They also work well for high-frequency and high-speed circuits. Engineers choose each material for the project’s needs. They look at things like thermal management and impedance control. Mechanical strength is also important.
Note: LT CIRCUIT’s way of picking materials makes sure every PCB Fabrication meets or goes beyond IPC-A-600 and IPC-6012 standards. These rules are for checking and testing PCBs in important areas like aerospace and medical devices.
The company can use different copper weights and laminates. This helps them make multilayer, HDI, and rigid-flex PCBs. These PCBs work well in tough places.
Precision Processes
LT CIRCUIT uses new ways to make PCBs with great accuracy. They use horizontal copper sinking. This keeps copper thickness change as low as ±3%. It is much better than old vertical plating. This method lowers defects and makes things faster.
Aspect | Traditional Vertical Plating | Horizontal Copper Sinking |
|---|---|---|
Copper Thickness Variation | ±15% | ±3% (6x more consistent) |
Processing Time | 45–60 minutes per batch | 25–35 minutes (40% faster) |
Defect Rate | 8–12% | 3–5% (with precise control) |
Chemical Usage | High (inefficient flow) | Low (optimized solution flow) |
Vacuum two-fluid etching lets them make very thin traces, down to 15μm. This is important for HDI PCB Fabrication. This method cuts copper undercutting by 80%. It also raises yield rates to 95–98%. Automated controls let them work all day and night.
Case studies show LT CIRCUIT’s methods lower defects in high-power server PCBs from 10% to 2.8%. Making aerospace PCBs is 30% faster. This helps finish hard projects quickly.
Quality Control
LT CIRCUIT’s quality control is better than normal. They have ISO 9001:2015 and ISO 13485:2016 certifications. This shows they care about quality and rules. Every PCB Fabrication gets checked many times. They use Automated Optical Inspection, X-ray, and flying probe testing.
They track all materials and steps for reliability.
Testing includes flying probe, functional, boundary scan, and reliability tests.
They follow IPC standards and product classes for steady quality.
Tip: LT CIRCUIT’s quality system supports Class 3 PCBs. These are needed for electronics that must work in tough places.
Customization
LT CIRCUIT lets customers customize complex PCB projects. The process starts with setting needs like frequency, impedance, and heat. Engineers pick the best materials and design the stackup. They use special layouts to cut signal loss.
Set needs and check performance
Pick materials for electrical and heat needs
Plan stackup for shielding and less EMI
DFM review to make sure it can be made
Design layout for high-frequency
Test and simulate for signal and heat
Make and check a prototype
Improve design after testing
Make the product with strict checks
LT CIRCUIT allows small orders, even just one piece. Fast prototyping gives bare boards in 24–72 hours. Assembled prototypes come in 3–5 days. They offer many substrates, copper weights, and via technologies. Clear pricing and quick supply help customers save money and meet deadlines.
Customization at LT CIRCUIT makes products more reliable. It also helps with heat and gives better performance in telecom, cars, and aerospace.
