We understand short and accurate lead time is essential in today’s rapidly changing market place. Customers need to know the exact date of the PCBs delivery so they can prepare the project schedule ahead of time. With Circuit engineering Co.,Ltd, lead time is considered as Printed Circuit Board Manufacture time + shipping time, no extra waiting time! Our standard lead-time starts from 5 to 9 working days, and 4 to 5 weeks for large volume production orders.
PCB board manufacturers use a wide variety of solder resist inks, which are essential for manufacturing of PCB boards. Judge quality of PCB Solder resist ink is basically determined by several factors such as viscosity, plasticity and fluidity. In addition, it is necessary to consider whether the formula is scientific and environmentally friendly. ViscosityThe abbreviation…
High Quality PCB Board Features include below aspects: After the components are assembled properly onto the PCB board, the electronic device should be easy to use, that is, the electrical connection should meet the requirements; The track width, track thickness and track spacing on the PCB board meet the requirements, so as to avoid heating,…
With the rapid development of the mobile phone, electronics and communications industries, and the continuous growth and rapid growth of the Printed circuit board industry, the requirements for the number of layers, weight, precision, materials, color, and reliability of components are increasing, as a result of that, the importance of Identify Printed Circuit Board Quality…
When engineers just entered the PCB maintanence industry, the most contacted are all kinds of PCB circuit boards. Attentive engineers can find that most of them Choose Green as PCB Solder Resist Color. Why? Painting is a technical requirement. First, both sides of the PCB are copper layers. In the production of PCB boards, the…
Printed Circuit Board, can be categorized according to its functions and utility as Aluminum substrates PCB with has been used widely on the scenarios where can generate great amount of heat and need to dissipate through the aluminium base which can be served as heatsink, high frequency PCB boards which can be used for the…
PCB Board is important component in the electronic product, is the carrier of electronic components and electricity connection provider. Traditional PCB Board use printed etching and solder resistance method to produce the circuitry pattern which comes its name. due to the increasing minimization and finest, most of the PCB Boards are applying the adhesive etching…
Static PCB Board Effect in PCB Manufacturing If a circuit displays sensitivity to Electrical Leakage in PCB Manufacturing, even the most rigorous cleaning can offer only a temporary solution. Problems soon return upon handling, or exposure to foul atmospheres, and high humidity. Some additional means must be sought to stabilize circuit behavior, such as conformal…
Static Circuit Board Effect Leakage resistance is the dominant static circuit board effect. Contamination of the PCB surface by flux residues, deposited salts, and other debris can create leakage paths between circuit nodes. Even on well-cleaned boards, it is not unusual to find 10 nA or more of leakage to nearby nodes from 15-volt supply…
High Density PCB Board Designing High density PCB Board designing is increasingly challenged by several factors: physical, finer pitch pin spacing, in-surfficient financial support, mounting must be very precise, and the environment limitation. Many plastic packages absorb moisture, causing the crack on assembly processing. Physical factors also include the complexity of the installation process and…
High Density Printed Circuit Board Design Global Trend Most people think the BALL GRID ARRAY package with mass chip scale as a feasible solution for portable electronic product to break the space limitation for High Density Printed Circuit Board Design. And it will simultaneously satisfy both the requirement for more complicate functions and performance. However…
