How to Choose the Right PCB Coating Machine Line Selecting the ideal equipment for your PCB coating line can be a complex task. In this article, we will guide you through the critical components of a standard PCB coating machine line and their solutions to common challenges. We'll delve into the line's composition, including the elevator, transfer station, coating machine, inspection station, curing oven, and their interconnectedness through a return conveyor. Let's explore each element and understand its role. Components of a PCB Coating Machine Line: Elevator: The PCB coating process starts with an elevator, efficiently transporting PCB boards to the next stage. Transfer Station: After the elevator, boards are conveyed to a transfer station, preparing them for the coating process. Coating Machine: The heart of the PCB coating line is the coating machine. We offer a range of coating machines, including I.C.T-T550, I.C.T-T550U, I.C.T-T600, and I.C.T-T650. Inspection Conveyor: Following the coating process, the boards move to an inspection station. The second transfer station is equipped with LED lights and a blue glass cover, enabling operators to closely inspect the coating quality. This feature is vital for ensuring consistent, dust-free coatings. Curing Oven: For UV-curable adhesives, we provide a UV curing oven to effectively solidify the adhesive. Return Conveyor: Beneath the entire line runs a return conveyor, connected to the elevator. This conveyor system efficiently returns PCBs from the last elevator to the first one, reducing manual handling and streamlining operations. The Advantages of the PCB Coating Line Design: 1. Easy Accessibility: The operator's station is strategically located beside the coating machine, ensuring easy access for setup and adjustments. 2. Enhanced Efficiency: The integrated return conveyor eliminates the need for manual transport, optimizing workflow. 3. Quality Control: The inspection station with the blue glass cover enables operators to inspect coatings for quality and cleanliness. 4. Dust Prevention: The blue glass cover also serves as a barrier to prevent dust contamination on freshly coated PCBs. Selecting the right PCB coating machine line is essential for achieving quality and efficiency in your operations. Our meticulously designed equipment line, along with its well-engineered components, can help you attain superior results. If you have further questions or need assistance in choosing the best solution for your specific requirements, please do not hesitate to contact us. We are committed to providing solutions that meet your needs and exceed your expectations....

Dispensing: A Robust Process Solution for Shield Edge Interconnect

Nov 06, 2023 | Rajiv L. Iyer and Michael L. Martel

A new process has been developed for RF shielding on compact electronic communications devices using automated solder paste dispensing. The process is known as Shield Edge Interconnect (SEI). SEI designs enable parts to be processed though underfill before placing of the RF shield and allows more complete use of valuable PCB real estate to achieve reduced form factor requirements and/or for added components on products such as smartphones and tablets. The reduced form factor creates challenges for the assembly of those devices. This process, enabled by Speedline dispensing technology, relies on extremely accurate dispensing of solder paste on copper traces located along the outer edge of the PCB. The result is a robust process solution for SEI in which proprietary closed loop dispenser, pump, vision, and software technologies enable a high volume manufacturing (HVM) process....

High Yield Embedding of 30um Thin Chips in a Flexible PCB using a Photopatternable Polyimide based Ultra-Thin Chip Package (UTCP)

Oct 24, 2023 | T. Sterken, M. Op de Beeck, F. Vermeiren, T. Torfs, L. Wang, S. Priyabadini, K. Dhaenens, D. Cuypers and J. Vanfleteren

A thin chip package for off-the-shelf ICs is developed which enables the embedding of these chips into a flexible circuit board. The package consists of a copper fan-out on a polyimide substrate, in which the thinned IC (30um) is embedded. These packages are subsequently integrated in a standard flexible circuit board (FCB). A microcontroller and a proprietary DSP processor are embedded using this technology. The yield of the Ultra-Thin Chip package (UTCP) was measured before embedding in the circuit board, and reaches up to 87% for the packaged microcontrollers (MSP430 family, known-good dies). The yield on the DSP processor was measured to be 62%. After embedding in the FCB, 95% of the functional UTCP-packaged dies are still functional....

Design and Fabrication of a PCB MEMS Module with Integrated Switches and Sensor Suite

Oct 09, 2023 | David Boteler, Nicholas Marsiglia, Ching-Yi Lin, Li-Anne Liew, Y.C. Lee

We demonstrate the feasibility of integrating Kapton-based MEMS capacitive switches and a sensor suite onto a printed circuit board with minimal impact to existing manufacturing processes. Copper-cladded Kapton laminates were bonded onto rigid PCB substrates with a BCB film spacer. The Kapton was patterned using reactive ion etching to produce MEMS structures such as suspended membranes and flexures. Atomic layer deposited alumina coatings were applied as dielectric layers for the capacitive switches and tilt sensors/accelerometers. The copper cladding was also patterned by etching to function as electrical leads, resistors, and capacitive electrodes. In this way, MEMS switches, tilt/acceleration sensors, temperature sensors, humidity sensors, and vacuum/pressure sensors, were all fabricated monolithically onto a PCB in a single module in the same fabrication process. We describe the fabrication process and demonstrate the functionality of the various sensors and switches in the module.
