Peelable Solder Mask

Peelable Solder Mask  For the partial masking of PCBs as protection from direct contact with solder or as protection in electroplating processes, simple/high-definition application by screen printing, very high elasticity and tear resistance, easy to remove before and/or after the soldering process Peelable Solder Mask PCB is the printed circuit board with peelable solder mask (a temporary solder mask), protected for some area during surface finishing or assembly process. That’s to say, sometimes printed circuit boards require protection of selected board areas during the Surface Finish or Assembly Process to keep solder from flowing onto contacts, terminals and plated through holes (PTH). Peelable [...]

IPC Releases 5 New Standards

IPC announces the release of five newly revised standards covering several areas of the supply chain.   IPC/WHMA-A-620D, Requirements and Acceptance for Cable and Wire Harness Assemblies IPC-2223E, Sectional Design Standard for Flexible/Rigid-Flexible Printed Boards IPC-2591-Version 1.1, Connected Factory Exchange (CFX) IPC-1791A, Trusted Electronic Designer, Fabricator and Assembler Requirements IPC- 6012E, Qualification and Performance Specification for Rigid Printed Boards PURCHASE NOW   Details on some of the changes for the newly released standards:   IPC/WHMA-A-620D provides several changes that were requested by the industry. The task group addressed the target conditions in the document by moving some conditions to acceptable [...]

Flexible PCB Design – Manufacturing – Assembly

Flexible PCB  , Flexible Circuit  or Flex PCB, is designed as a replacement for traditional wire harnesses, Is soft PCB board  compared with Rigid PCB. Flexible PCB can be manufactured as single-sided, double-sided or multilayer plated through printed circuit boards. This allows the complete wiring of compact devices and systems with the advantage that no additional cables or plug connectors will be required. Flex designs pose unique challenges for most PCB tools because traditional object checks don’t account for Flex check nuances. They present a new set of objects that are best accounted for during the design phase. This forces [...]

PCBA assembly Appearance Inspection Instructions

Printed circuit board assembly (PCB assembly, PCBA), often use abbreviations—— PCBA, is an important electronic parts, is the support of electronic components,the provider of the electronic circuit connection.Because it is produced by using electronic printing technology, it is called "printed" circuit board.Before appears in the printed circuit board, electronic components of interconnection between relied on wires connected directly and form a complete circuit. Now, the circuit bread board only to exist as an effective experiment tool,but the printed circuit board in the electronics industry has become the dominant position. But most people still don't know what is PCBA  appearance inspection [...]

Uses of Ceramic PCB

The ceramic PCB made on ceramic is considered a type of metal core PCB. While other circuit boards such as FR4 PCB or Aluminum PCB can be used for electrical equipment, Ceramic circuit boards provide extra safety. The PCB also keeps the devices risk-free. Typically, Ceramic board is used in the followings: Spotlights and high-current LEDs Exchange converters Power controllers Variable optical systems Power regulators for cars Industrial power equipment Semiconductor refrigeration devices IC arrays Printers Audio amplifiers Solar cell substrates High power transistors and transistor arrays Power applications Ceramic PCB’s high electrical insulation and high-temperature resistance performance refrain electrical [...]

Printed Circuit Board Assembly

Printed Circuit Board Assembly The circuit board before the assembly of electric components is called Printed Circuit Board. After the soldering of all the elements on the board, it is known as Printed circuit Board Assembled. The complete process of component's assembly is called Printed Circuit Assembly or Printed Circuit Board assembly or PCB board assembly. In this process, different automatic and manual assembly tools are used. We are assembler that offer PCB assembly. PCB boards cannot perform any function until and unless its assembly is completed. PCB assembly is a process of assembling and soldering electrical parts on a [...]

5 Questions to Ask PCB Manufacturer and electronic assembly services ltd

5 Questions to Ask PCB Manufacturer and electronic assembly services ltd With so many PCB manufacturers and PCB assembly suppliers to choose from, it's easy to feel overwhelmed with picking the right one. This may come as a surprise, but not all PCB manufacturers  and PCB assembly manufacturers are created equal.  In fact, by asking these questions before you choose a PCB manufacturer, you'll get to see firsthand how some manufacturers simply don't measure up to others. 1.How many years have you been in business? When it comes to manufacturing circuit boards, experience is everything. This question not only sheds light on a [...]

Specifications for the manufacture of aluminum base PCB

The aluminum boards produced by Aluminium PCB manufacturers are mostly used for LED PCB lamps. What are the specifications for the production of aluminum base board in the production process? Aluminum boards produced by aluminum board manufacturers are often used in power devices, and the power density is large, so the copper foil is relatively thick. If a 3 oz or more copper foil  is used, the etching process of the thick copper foil requires engineering line width compensation, otherwise, the line width after etching will be excessive. The surface of the aluminum boards produced by the aluminum board manufacturer must be protected with [...]

What is Ceramic PCB? Differences between PCB & Ceramic PCB

PCB or printed circuit boards are made by printing conductive pathways into a board that connects transistors, resistors, and integrated circuits.   In the case of Ceramic printed circuit boards (Ceramic PCB), the conductive pathways are printed in ceramic baseboards. This essentially improves the performance quality of such circuit boards. The ceramic used in this case is not the typical ones that are utilized in floors; instead, it is a special kind of material called ‘fine ceramic.’ It is engineered with different chemical substances for specific uses. A ceramic printed circuit board is made of metal cores. Aluminum nitride boards [...]

The difference between Core and Prepreg

The Prepreg is an insulating material for the PCB. Prepreg is not prepreg before being laminated, also known as prepreg,prior to lamination, and is primarily used as a bonding material and an insulating material for the inner conductive pattern of a multilayer printed circuit board. After the Prepreg is laminated, the semi-cured epoxy is extruded, begins to flow and solidifies, bonds the multilayer sheets together and forms a reliable insulator.   The Core is the basic material for making printed circuit boards. The Core is also known as the core board, which has a certain hardness and thickness, as well [...]
