Dferrantielectronics is design many of PCB assembly in high reliability because printed circuit assembly is at the heart of your product.
The controller operates at TTL logic level (0-5V) whereas the serial communication in PC works on RS232 standards (-25 V to + 25V). This makes it difficult to establish a direct link between them to communicate with each other. The intermediate link is provided through MAX232. It is a dual driver/receiver that includes a capacitive voltage generator to supply RS232 voltage levels from a single 5V supply. Each receiver converts RS232 inputs to 5V TTL/CMOS levels. These receivers (R1 & R2) can accept ±30V inputs. The drivers (T1 & T2), also called transmitters, convert the TTL/CMOS input level into RS232 level. goo.gl/A5s5Fw

What is PCB with Metal Dome
Metal shrapnel (also known as pot or piece, metal dome, snap dome), made of ultra-thin (0.05mm-0.1mm thickness) and ultra-thick (usually high hardness) stainless steel 301 or 304 material. Metal dome is an important part of the PCB membrane switch.
They are momentary switch contacts that become normally-open tactile metal dome switches when used in conjunction with a printed circuit board (PCB).
PCB is also known as printed circuit boards because it is made by electronic printing. A printed circuit board is a substrate for assembling electronic components and is a printed board on which a point-to-point connection and a printed component are formed on a general-purpose substrate in a predetermined metal core printed circuit board design.
Metal domes can be divided into several groups: round metal dome, triangle metal dome, rectangular metal dome, four-leg metal dome(cross shape), square shape metal dome and other special shapes. PCB membrane switches are widely applicable. It can be applied in areas including mobile phones, diagnostic equipment, industrial controls, test equipment, and measurement equipment, etc.

What we can do in PCB products
We are one of the trustworthy metal dome switch suppliers. However, PCB assembly is also a very important component for metal dome membrane switch. To meet customers' requests and demands, we have a professional team to help the customers change the PCB circuit into a Polyester printing circuit. There are some designs with space limit which need to be changed from the Polyester circuit or flexible circuit into Double-side or Multi-layer's PCB. That's also one of the services we can provide. In addition, we can provide some PCBA services, such as solder the components and assembling metal dome and different layers' (Overlay, Spacer) in PCB.
This PCB assembly (there is a small daughterboard) carries the RS232 connectors, breakout box switches, LED drivers and LEDs and also the parallel port connector (DB25, but not wired as a PC printer port!) and the current loop connector (DE9) with the current loop input optoisolator alongside it.
Denis Ferranti Technology offers automated box build services that connect with highest marketplace standards. In relation to building some sort of Printed Circuit Board (PCB) pertaining to electromechanical assemblies there several stages required at distinct levels.
The tip contact block that plugs into the laptop (Compaq in the example tip above) was premolded then soldered to the PCB where the solder joints were a weak point and would fracture in use. The PCB assembly was encapsulated as the second shot. The very slight molding gap surround was enough to allow flexing that eventually weakens then breaks the soldering to the front connector block.

Almost every medical equipment requires a fully assembled medical circuit board. Ultrasonic therapy equipment and blood pressure monitors are a few examples of standard medical equipment, and all of them count on PCBs to kick in. HX technology aims to provide multiple high-quality medical device products, including ultrasound machine PCB, endoscope PCB and glucometer PCB board.
The trend of PCB Medical Industry
The medical field is not like it used to be. Advances in technology have revolutionized the industry. This change is even more evident in electronic diagnostic, research, and treatment systems and tools. Every day, several complex electronic devices and instruments are introduced to simplify various medical procedures. This growth has largely benefited the PCB industry because, without PCB, new inventions would not be impossible. To meet the ever-changing needs of medical device and diagnostic machine manufacturers, today's PCB manufacturers are manufacturing extremely simple parts into highly complex printed circuit boards in PCB medical industry. Using specialized high-speed laminates, copper and aluminum substrates, ceramics, and coatings, PCB manufacturers can make these boards best suited for medical industry applications.
Applications of PCB for Medical Industry
With the development of medical technology, more and more medical diagnostic, research and treatment have advanced, which need computer-aided. It means that medical devices and equipment must have a high level and high precise standard of medical PCB. Therefore, medical PCBA has become more important in medical fields, which is the PCB meaning in medical.
The rapid progress of medical science today is closely related to the development of the electronics industry. A lot of microbiological equipment and other instruments are individually based PCB, such as pH meter, heartbeat sensor, temperature measurement, ECG machine, EEG machine, MRI machine, X-ray, CT scan, blood pressure machine, blood glucose level measurement equipment, incubator, and some other medical equipment.
Custom Medical PCB Assembly
Customization of medical PCB assembly is the trend today. The medical industry has chosen the same approach when it comes to PCB. Customers can provide the correct specifications with the full form of PCB in medical for board size in X-direction, board size in Y-direction, total number of holes, minimum alignment and pitch size in inches, board material, number of layers, surface coating, etc. Therefore, the manufacturer will work according to the given specifications and deliver the right product for your application.

Turn-key PCB Assembly Quality Control Process
Assembly manual instruction
The PCBA engineer make the assembly manual instruction to norm the manufacturing process in advance, guide the production, and improve the quality from the process technology.
IQC Incoming Quality Control
Check all the components values, pads size, brands, manufacturing date and code.
SPI Solder Paste Inspection
Solder paste inspection can check the solder paste is sufficient and uniform to prevent assembly quality problems in advance caused by poor solder paste soldering.
Online AOI Inspection
The AOI can check the short circuit, offset, wrong solder, reverse solder, false solder, empty solder, incomplete solder, etc. It also can check excessive solder, less solder, continuous solder and solder joints.
First sample confirm
Check the first sample with Gerber, BOM and coordinate files, test it’s function with the testing program. Only sample confirmed by PCBA engineer, it can go for mass production.
Off-line AOI inspection
Check the soldered surface mount assembly for errors, omissions, and false connections.
X-Ray welding inspection
Inspect the solder joints of invisible components like BGA.
QC manual inspection
The assembled board is visually inspected to ensure 100 % ok.
