With the rapidly increasing complexity of assemblies, electrical verification at the prototype level has become a necessity to meet time-to-market requirements. Flying Probe (or Fixtureless) test allows your engineers to focus their efforts on prototype design verification, instead of debugging process issues. Flying Probe test development is low cost and very fast, making it an ideal tool for prototype verification. There is no fixture to purchase, eliminating costly tooling procurement and allowing the ultimate in flexibility to incorporate design changes. Often used in a combinational strategy with AXI or AOI, Flying Probe allows detection and repair of electrical defects such as wrong parts, reversed parts, missing parts, solder opens, and solder bridges before they are in your engineer hands. Flying Probe at Topscom can help you improve your products time-to-market at the highest possible quality levels. is.gd/EWoJq8

Printed Circuit Board Assembly is a process that requires knowledge not just of Printed Circuit Board components and assembly but also of printed circuit board design, Printed Circuit Board fabrication and a strong understanding of the final product. Circuit board assembly is just one piece of the puzzle to delivering the perfect product the first time.
Printed Circuit Boards (PCBs) are across many industrial and consumer electronics. The versatility of PCBs comes from their lightweight, compact, and flexible construction, which can be adapted to suit circuits of any complexity. Though PCBs are relatively commonplace, their complexity makes it critical to source new circuit boards from reliable suppliers. Printed Circuit Board Assembly services harness these complexities.
Hitech Group offers comprehensive Printed Circuit Board Assembly services that help our customers fully realize their designs. We have extensive experience working with customers in a broad range of highly innovative industries, including Communication, Automotive, Industrial control, Medical equipments, Oil & Gas, Security, and so on.
Turnkey services reduce the time customers spend contacting multiple suppliers during PCB assembly and manufacturing. Compared with the traditional PCB assembly method, a scientific order arrangement system enables customers to obtain higher-quality and lower-cost PCB assembly products in a shorter time. Turnkey services can prototype a PCB within 12 hours and assemble the prototype within 24 to 7 hours, even without a minimum quantity requirement. Of course, the services of PCB manufacturing, component procurement and PCB assembly can be selected separately or in combination.
The PCB assembly process, also known as PCBA (Printed Circuit Board Assembly), involves several technical steps, including component placement, soldering and rigorous testing. Two main techniques were used:
SMT (Surface Mount Technology) : Directly installing components onto the surface of a PCB.
THT (Through-Hole Technology) : Components are inserted through holes and soldered to the other side of the circuit board.

Topscom has a focused staff of Test Development engineers dedicated to Functional Test development. With the ownership of Functional Test in-house, tester transition and support are efficiently managed.
• Functional Test Development Links
• Test Fixtures
• Target Tester
• Functional Test Development Overview
As a full test service provider, the Functional Test Developers at Topscom can improve an existing test system or design new test solutions to meet a specified test strategy. Key services include the use of Topscom standard testers. Standard testers include testers based on VXI, PXI (Target Tester) and GPIB instrumentation schemes. The best fit tester is applied with regard to a number of test strategy factors. The choice of a Topscom standard tester allows for expeditious development over a wholly custom solution. Additionally, Topscom owns and maintains the tester rather than contacting the Customer or a third party test vendor for calibration, maintenance, and trouble shooting. Topscom also excels in custom test development. Though not necessary, a standard tester is often the starting point of a custom tester where product specific instrumentation is added to the tester. is.gd/gGdgBt

Heavy copper pcb manufacturering
Hitech is a professional heavy copper pcb, thick copper pcb board manufacturer, PCB power supplier from China, we have been associated with heavy copper pcb plating since 2000 and we have won good reputation in this industry. If you have customized heavy copper pcb needs, please don’t heisitate to conatct sales12@hitechcircuits.com.
What is heavy copper PCB board
Heavy copper PCB boards ( also being called thick copper board, power board etc ) are usually bonded with a layer of copper foil on a glass epoxy substrate. The thickness of copper foil is usually 18μm, 35μm, 55μm and 70μm. The most commonly used copper foil thickness is 35μm. The thickness of copper foil used in China is generally 35-50μm, and there are also thinner ones such as 10μm and 18μm; and thicker ones such as 70μm. The thickness of the composite copper foil on a substrate with a thickness of 1-3mm is about 35μm; the thickness of the composite copper foil on a substrate with a thickness of less than 1mm is about 18μm, and the thickness of a composite copper foil on a substrate with a thickness of more than 5mm is about 55μm. If the thickness of the copper foil on the PCB is 35μm and the printed line width is 1mm, then for every 10mm length, its resistance value is about 5mΩ, and its inductance is about 4nH. When the di/dt of the digital integrated circuit chip on the PCB is 6mA/ns and the working current is 30mA, the resistance and inductance contained in each 10mm printed line are used to estimate the noise voltage generated by each part of the circuit to be 0.15. mV and 24mV.
Advantages of heavy copper PCB board
Heavy copper plate has the characteristics of carrying large current, reducing thermal strain, and good heat dissipation.
1. The heavy copper circuit board can carry large current
In the case of a certain line width, increasing the copper thickness is equivalent to increasing the cross-sectional area of the circuit, which can carry a larger current, so it has the characteristic of carrying a large current.
2. Heavy copper circuit boards reduce thermal strain
Copper foil has a small electrical conductivity (also called electrical resistivity ), the temperature rise is small when a large current is passed, so it can reduce the amount of heat and thereby reduce the thermal strain.
Metal “conductors” are divided into: ” silver→copper→gold→aluminum→tungsten→nickel→iron ” according to conductivity.
3. The heavy copper circuit board has good heat dissipation
Copper foil has high thermal conductivity (thermal conductivity 401W/mK), which can play an important role in improving heat dissipation performance, so it has good heat dissipation;
Thermal conductivity refers to the heat transfer through an area of 1 square meter within 1H for a 1 meter thick material with a temperature difference of 1°C on both sides under stable heat transfer conditions, measured by W/m·K.
Applications of heavy copper PCB board
The application field and demand for thick copper plates have been rapidly expanded in recent years, and it has become a “hot” PCB variety with good market development prospects.
The vast majority of heavy copper PCBs are high-current substrates (current x voltage = power). The main application areas of high-current PCBs are two major areas: power modules and automotive electronic components. Some of its main terminal electronic product fields are the same as conventional PCBs (such as portable electronic products, network products, base station equipment, etc.), and some are different from conventional PCB fields, such as automobiles, industrial controls, and power modules.
High-current PCBs are different from conventional PCBs in terms of efficacy. The main function of a conventional PCB is to form a wire for transmitting information. The high-current PCB has a large current through it, and the main function of the substrate carrying the power device is to protect the current carrying capacity and stabilize the power supply. The development trend of such high-current PCB is to carry larger currents, and the heat emitted by larger devices needs to be dissipated. Therefore, the large currents passing through them are getting larger and larger, and the thickness of all the copper foils of the PCBs is getting thicker and thicker. The 6 oz copper thickness of the high-current PCBs manufactured now has become normal;
The application areas of heavy copper circuit boards include: mobile phones, microwaves, aerospace, satellite communications, network base stations, hybrid integrated circuits, power supply high-power circuits and other high-tech fields.
