Seeed Fusion Service Ensures High-Quality PCB Assembly at every stage

Seeed PCBA inspection and manual re-work station

Quality is as important to us as it is to you. At Seeed Fusion, our manufacturing expertise can help you reduce errors and failure rates for a prototype or a mass-produced product. Whether there is a problem with one of the components, assembly, or the PCB design itself, any error can result in a non-functioning device which can be complicated or impossible to rectify. In the business for over 10 years, Seeed is an old hand when it comes to manufacturing electronics and implements quality control measures at every stage of its Seeed Fusion PCB Assembly service.

Gerber File Review

Quality assurance procedures begin at order submission. CAM engineers will review every set of manufacturing files to minimize design for manufacture errors before the files are sent for production. As the old saying goes, prevention is better than cure. If any problems are found such as shorts and breaks, missing holes or solder mask openings, etc. Seeed Fusion will work with the customer to review the issue and make corrections if necessary.

PCB In Production

As standard, all Seeed Fusion PCBs undergo bare PCB AOI (Automated Optical Inspection), flying needle tests, individual visual checks between each stage and then a Final Quality Control inspection. These measures cover errors with copper deposition, trace connectivity, solder mask coverage and more.

Incoming Parts Quality Inspections

Many fake, second-hand or old components are on the market, so vigilance is paramount when shopping for parts. Seeed Fusion’s PCBA service can take the risk out of parts procurement for you. Seeed preferentially orders its components from partners DigiKey, Mouser, TME and Element14 to ensure genuine and new parts direct from reliable channels.

Seeed’s own stock of parts, the Seeed Fusion Open Parts Library (OPL) also undergo strict quality control measures to fulfill high standards. All incoming stock goes through the same IQC (Incoming Quality Control) that Seeed’s own materials undergo and suppliers are trusted partners that are audited on a regular basis.

Assembly Process

Seeed Fusion PCBA’s completely lead-free assembly line employs visual inspections along the entire line as well. Each operator at each stage will check for common process errors, for example, PCBs fresh from the reflow oven will be inspected for insufficient solder wetting, component tombstoning or skew, etc. and re-worked if necessary. Boards are then inspected before packing, and any issues that arise are forwarded to the customer for confirmation.

Other tests and certifications are also available such as mechanical and functional testing, In-Circuit testing, SMT AOI, X-ray inspection, FCC/CE certification and more.

Increase Arduino UNO memory with ATmega2560

An Arduino UNO Flash and RAM update with the ATmega2560 as DIL 28 variant.

I love the Arduino UNO with the DIL 28 ATmega328. He is easy to replace and all my projects are equipped with it. But constantly either the flash memory, the RAM or both is too small. Therefore, I have developed a replacement that provides 8 times more memory. For this I went into the microcosm of the PCB construction and impressed an ATmega2560-16CU in the smallest possible layout.

3D Printed Clip-On Turns Any Smartphone To A Household Microscope.

Smartphone microscope as the name implies is basically a microscope which is compatible with a user’s smartphone. They mostly made up of a soft pliable lens and uses the smartphone’s camera. Smartphone microscopes have been in existence before, they are based on the use of external LEDs and usually get powered from an external source, these attachments have been quite larger and more cumbersome than the phone itself, but a group of Australian researchers has developed a microscope attachment that doesn’t require an additional power supply or external light sources which is actually based on 3D printed material alone.

The Researchers from the ARC Center of Excellence for Nanoscale BioPhotonics (CNBP) have developed a 3D printable “clip-on” that will allow anyone to turn their smartphone into a fully functional microscope. Thinking about the weight and cost of the pre-existing smartphone microscopes, they have made a dual-mode mobile phone microscope which uses the onboard camera flash and natural light present at the scene where the microscope is to be used. If a sample is placed two focal lengths in front of the objective lens, an image is formed two focal lengths behind the tube lens.

The invention of this microscope will make sure that people unable to afford pre-existing microscopes due to the cost of the external electrical appliances to be added during assembly can now work on their research as long they have a smartphone and the 3D printable microscope. They can examine different samples ranging from plant cells to animal cells. The smartphone microscope’s design consists of a 1x magnification imaging system that is created by placing a mobile phone camera lens in front of the mobile phone’s internal phone camera module.

The difference between the 3D printable microscope and other smartphone microscopes is the illumination system of the 3D microscope since it has been designed with internal illumination tunnels. The entrance of the tunnel is placed over the camera flash. Light from the camera flash travels through the first tunnel, reflects diffusely off of the end of the tunnel and then travels back into another tunnel that is aligned to the optical axis of the objective lens and camera module.

This 3D printed based microscope has the ability to work in two different modes: the brightfield and darkfield imaging modes respectively. During the bright field mode, the microscope creates diffuse transmission illumination without the aid of an external reflective object behind the sample thereby reducing weight and cost procured upon the addition of an external electrical object. However darkfield imaging is made possible when the ambient light illuminates the sample using the sample’ glass slide. The microscope attachment is capable of viewing objects as small as 1/200th of a millimeter, making it significantly more effective than its more predecessors.

The 3D printers microscope needs only one assembly step and can be used by anyone with access to a 3D printer as the microscope clip can be printed using most makers set of 3D printers. You can get the 3D designs here if you are interested in printing out your own.

Fan Speed Control Is Cool!

App note from Maxim Integrated about their MAX6650 and MAX6651 fan controllers chip.

Temperature-based fan control is a necessity in a growing number of systems, both to reduce system noise and to improve fan reliability. When fan control is augmented by fan-speed monitoring, a speed-control loop can be implemented that is independent of manufacturing variances and wear on the fan. In addition, a fan that is about to fail can be identified so that it can be replaced before it fails.

The New Raspberry Pi 3 Model B+ Offers More Power, More Speed and Faster Ethernet

Two years ago, we saw the announcement of the ever lovely Raspberry Pi 3 which packed a lot of improvements to the Raspberry Pi 2. But what about making it even better? Welcome the Raspberry Pi 3 big brother – The Raspberry Pi 3 Model B+ or just called the Raspberry Pi 3 B+ and guess what? It’s being launched on March 14, the Pi day and the day we lost Stephen Hawking.

Ever since the first Raspberry Pi was launched back in 2012, we have seen a rapid improvement in the whole Raspberry Pi family and even a deviation from the standard credit-size form factor as we saw in the Raspberry Pi Zero and the Zero series (Zero W and Zero WH),. Since then it cemented its status as the undisputed “King” in the world of SBCs (Single Board Computers). The latest iteration of this family called the Raspberry Pi 3 Model B+ has the same footprint as both the Raspberry Pi 2 Model B and the Raspberry Pi 3 Model B but even greater features.

The Pi 3 Model B

The Model B+ major improvements come from its processor and networking capabilities, it sports a 64bit 1.4GHZ quad-core Broadcom BCM2837B0 processor as compared to the 1.2GHz BCM2837 chip in the Pi 3, dual-band 2.4GHz and 5GHz 802.11ac Wi-Fi connectivity, Bluetooth 4.2/BLE and Gigabit Ethernet with maximum transfer network speeds of up to 300 Mbps (three times the speed of the previous boards).

The Pi Foundation says this processor improvement is made possible as a result of improved power integrity and thermal design. The dual-band Wi-Fi on the board also comes with compliance certification, making it easy to integrate into end products without the hassle and cost of certification requirements. Just as the previous model, the Raspberry Pi 3 Model B, the Model B+ also comes with a full-size HDMI Port for video and display output, four USB 2.0 ports, a microSD port for storage purposes and booting OS, CSI ports for the Raspberry Pi camera, DSI port for connecting touchscreen displays, and also provides support for Power over Ethernet (PoE) through a PoE HAT Add-on which is sold separately.

With this improvement on the Pi 3 Model B+, the hopes are high for the Raspberry Pi 4 making us wonder what  would be added into the future Raspberry Pi 4, but for the time being, let’s rock our too good to be true Pi 3 Model B+. The Model B+ is available from Raspberry Pi’s official retail partners, and price remains the same too, meaning it’ll cost $35/£30 at the usual suppliers.

IQ Motor Module – An Integrated Motor With A Closed Loop Controller And Position Sensor

The drone industry is booming, and the technology is just… cool, to put it plainly. Flying robots, many of which are completely autonomous delivering our goods and also spying on us. Makers and hobbyist are getting on the bandwagon, making their customized drones with available parts. With the boom of UAV (Unmanned Autonomous Vehicle) and Drone technology also comes the growth of issues.

IQ Motion Module

Electric motors are one of the most fundamental parts of electric based flying objects like drones. Drones usually use brushless DC paired with an ESC (electronic speed control) unit for speed regulation and a possible flight controller for position handling. Building your own drone either for the fun of it or a special purpose means you have to go through the hurdle of selecting the Motors, ESC, controller etc. You also have to choose which strength to prioritize and not to mention of potential compatibility or over/under powering issues. But with IQ Motor Module, you don’t have to worry about all those. The drone industry has relied on hobby-grade motors and controllers for too long. Now, IQ is bringing advanced motor control to the drone industry and other robotics fields at an affordable price.

The IQ Motor Module from IQ Motion Control is an integrated motor and controller with an embedded position sensor that is designed to change some of the challenges faced with drone, flying object set up by combining all of those capabilities (motor, electronic speed control, controller, position sensing) into a single versatile unit. The module is made up of three major components: a brushless DC motor, a motor controller, and a position sensor. With position-sensing and advanced calibration and control algorithms, IQ can optimize motor performance and give users unprecedented control over their vehicles and machines.

The IQ module provides serial communication interface as well as standard hobby protocols making it widely compatible with the possible vehicle and drone design. It also comes with some features built in like, a 40 ms response time, over-current protection, active freewheeling, anti-cogging, mo delay with zero crossing, jitter-free startup, regenerative and active braking, and many others. The velocity and position control is based on a tunable PID + Feed Forward control.

The controller is built on a 32-bit 64 MHz Arm Cortex MCU and has two firmware options, a high-speed module, and a precision module both in a 2306 size. The high-speed module provides a constant rpm of 2200 KV, and the precision module a constant rpm of 220 KV. Both motor will have an estimated peak current of 30 A and estimated peak voltage of 25.2 V. The speed firmware is specially designed to drive propellers or any application with a target velocities. A position firmware for precision is useful for 3D printers, robots, and machine tools. The firmware can be reflashed at any time by the user, so you can always reuse your IQ Motor Modules. It comes with a power and efficiency boost; Sinusoidal commutation to give a 20% increase in battery life and Trapezoidal commutation to provide about 4.8% more shaft power.

The IQ Motor Module is suitable for a wide variety of applications including consumer and enterprise drones, as well as many other robotic projects. The new IQ Motor Module will offer “unparalleled performance.” You can back the Crowd Supply campaign until May 10th, and a single IQ Motor Module will cost you $80, or $305 for a pack of four. Orders will be shipped in September 2018.
