One-Stop PCBA Services

PCBA Process Overview

LTPCBA helps you from start to finish. They guide you from design to testing. The process has many steps for strong circuit boards. Here is what happens:

First, you design your board and get files ready. EDA tools help you make the layout and files.
Next, LTPCBA finds all the parts you need. They get every part for your board.
Then, they make the board using your files. This step builds the real circuit board.
Solder paste goes on the board pads.
Machines put parts on the board.
Soldering connects the parts to the board.
Tests and checks make sure your board works well.

PCB Manufacturing

LTPCBA is a top choice for making circuit boards. They use smart machines and computers for each step. Laser stencils, X-ray, and AOI help them check for mistakes. You get your boards fast, even for small or medium orders. They can make many types and sizes of boards, so your project goes smoothly.

Aspect	Details
Automation	Smart lines, laser stencils, AOI, X-ray checks
Delivery	Samples in 24 hours, small orders in 72 hours, medium in 5 days
Capacity	SMT: 4 million parts/day, THT: 500,000 parts/day
Board Types	Hard, bendy, metal boards; up to 400mm x 1200mm

Component Procurement

You want only good parts in your board. LTPCBA uses a strong system to buy parts. They pick trusted sellers and use smart plans to avoid problems. You get good quality and clear prices. This keeps your project on time and costs steady.

One-stop service means fewer mistakes with suppliers.
Early checks find problems before you get the board.
Extra parts and many suppliers keep work moving.

Assembly Methods (SMT, THT)

Your board can use SMT or THT ways. SMT puts small parts on top, making things smaller and lighter. Fast SMT lines help make more boards and save money. THT puts parts through holes for extra strength. Both ways together help your board work for any job. LTPCBA checks each step with AOI and X-ray to make sure it is right.

PCBA Testing and Final Assembly

In-Process PCBA Testing

You want your board to work right away. LTPCBA checks for problems early. AOI looks for missing or wrong parts. X-ray finds hidden solder issues inside the board. ICT tests if each part works. Functional testing checks if the board does its job.

You see these steps in every test:

AOI looks for surface problems.
X-ray checks under chips and inside solder.
ICT tests wires and values.
Functional testing runs the board for real use.

Test tools include AOI, ICT, and software. Each test follows clear steps and keeps records. Machines are checked often for accuracy. If a problem shows up, teams find and fix it fast. Everyone works together to make things better.

Note: Testing during the process stops big mistakes later. Finding problems early saves time and gives better boards.

Final Assembly

After tests, your board goes to final assembly. LTPCBA puts all parts together and checks each one. Machines place parts with almost perfect accuracy. Automated systems handle paste, placement, and soldering. This lowers mistakes and speeds up work.

Metric/Process Aspect	Description/Value	Impact on Quality and Reliability
First Pass Yield	95% target	Less rework, faster delivery
Pick-and-Place Accuracy	99.95%	Precise placement, fewer defects
AOI and ICT	Used at every step	Early defect detection
Inspection Time	Much shorter with automation	Faster quality control
Solder Paste Application	Controlled by stencil and thickness	Over 70% of welding success depends here
Reflow Soldering	Precise temperature control	Consistent solder joints
Final Testing	Functional, electrical, durability, strength tests	Confirms reliability before shipment
Statistical Process Control	Data-driven quality control	Consistent quality, process improvement

Bar chart showing LTPCBA efficiency metrics: 95% FPY, 99.95% pick-place accuracy, and 70% solder paste success

Final assembly is more than just putting parts together. You get more tests for function, electricity, and strength. These steps make sure your board lasts and works well. LTPCBA tracks every step with data. Machines are kept in good shape for smooth work.

Quality Assurance

Quality checks are very important at LTPCBA. You get strong testing at every step. AOI, x-ray, ICT, and other tests catch any problem. LTPCBA follows world rules like ISO and UL. This makes you trust every board you get.

LTPCBA uses many tools for quality:

AOI and x-ray find visible and hidden problems.
ICT and flying probe check the electric parts.
Functional tests show if the board works in real life.
Solder paste and burn-in tests add extra checks.

The company keeps records for every test. If a problem happens, teams fix it and stop it from coming back. LTPCBA’s 99.5% pass rate proves their quality. You get boards that meet tough rules.

Tip: Quality checks happen all the time, not just at the end. Every step matters, from start to finish.

Packaging & Delivery

When your board passes all tests, LTPCBA gets it ready to ship. They use special packaging to save money and protect your board. Anti-static bags and foam stop water, static, and bumps. Clear labels help avoid mistakes.
