PCB Assembly Process
1. PCB Manufacturing
loctite solder paste
PCB design & fabrication helps you with experienced PCB design and fabrication, high accuracy, quality control. PCB Assembly includes layout, fabrication and assembly. We also have monthly abilities of offering 35,000 square meters PCB, 80 million point SMT and introduce ICT, flying probe, AOI, X-ray, function test, burn-in test into inspection phase. We can help you with a system of transforming natural resources, raw materials and components into a finished product that is delivered to the end customer and strive to have the most optimized supply chain to make efficient and costs lower.
2. Screen Printing of Solder Paste onto PCB Board
loctite solder pastePhysicochemical and process property of solder paste directly impact SMT soldering quality. Solder paste printing is applicable for placing appropriate amount solder paste onto PCB pads, in order to ensure good circuit connection between SMT components and PCB pads and their mechanical strength. Solder paste printing is the critical process of SMT. Metal template printing is conventionally applied so far. According to related statistics, 60%~70% quality problems are caused by solder paste printing in premise of quality guarantee of components and printed circuit board. Requirements of solder paste printing:
a. Place solder paste appropriately, evenly and uniformly. Solder paste shape is clear and neighbor shapes do not connect. Solder paste shape is in compliance with that of pad, without any dislocation.
b. In general, the unit area solder paste amount should be 0.8mg/mm2, particularly 0.5mg/mm2 for narrow-pitch components.
c. After solder paste printing, the shape has no heavy collapse and edges are trim. Plate surface is not allowed to be contaminated by solder paste.
There are a large variety of solder paste with different alloy compositions, granularity and viscosity even for all from one manufacturer. How to choose appropriate solder paste highly impacts the product quality and cost. Now NOD Electronics is using Loctite lead free solder paste. We have figured out Loctite solder paste is reliable to ensure good product quality after process engineering test of its printability, demoulding, thixotropy, cohesiveness, wettability, welding spot defect and residue.
3. Lead-free PCB Assembly
In light of environmental concerns and customer request, we can offer lead-free PCB assembly which complies with RoHS standards. At upstream, we choose PCB laminates in compliance with RoHS standards for PCB manufacturing. Also we use lead free solder paste and related reflow/wave ovens. We strictly fulfill RoHS requirements in light of your local regulations and don’t want to make you into any trouble on this basis.
4. Burning Program and In-Circuit Test (ICT)
Our test engineers will check short circuit, voltage, current, signal transmission of PCB assembly boards according to your ICT test plan. A professional report will be handed up to you if for any detected problems. For batch order, we design exclusive test frames to fast the ICT test process. We are also well sophisticated with decoding and burning program for you. Related test frame will be built to ensure products work effectively according to your requirements.
We also have a refined management of following phases of PCB assembly.
Incoming materials management
Surface mount technology (SMT)
Through hole technology (THT)
In-circuit test (ICT)
PCB assembly equipments
PCB assembly workflow

How to Abtain PCB Assembly Quote
PCB assembly price in quote depends on PCB manufacturing, components, test plan and order quantity. PCB manufacturing cost is easily calculated by its dimension, layer(s), copper thickness, laminate thickness, surface finish and other special engineering requests (such as heavy copper, impedance, blind via, buried via etc), but components cost is hard to estimate, because different boards have its designs (using different ICs, connector etc).
To obtain an official quote, please send your Gerber files, bill of materials (BOM) and the quantity required to email@example.com. We will get back to you with a quote within one business day.
We are striving to offer best PCB assembly services from China to global regions. All kinds of PCB assembly problems which could not be fixed in other supplier will be resolved by our excellent engineering and manufacturing team. That’s why 100+ customers come close to us. We have capabilities of organizing incoming raw materials, process control, refined test to offer you best PCB assembly services in terms of small-to-large volume production quantities. During the course of PCB assembly, our engineers will report a DFM report if for defect in relation to PCB design and PCB manufacturing.
