Flying Testing of PCB The open PCB circuit test principle of the flying probe test is the same as that of the needle bed test. Two probes in the PCB board are connected to the end of the network at the same time to energize, and the obtained resistance is compared with the set open PCB circuit resistance to determine whether the open circuit is open or not. Flying probe test of PCB manufacturing has the following advantages: Short test development cycle, Relatively low test cost, High conversion flexibility.
Resin plug hole of PCBUse resin to plug the buried hole of the inner HDI, and then press it. This process for printed circuit board balances the contradiction between thePCB thickness control of the laminated dielectric layer and the PCB design of the inner HDI buried hole filler. If the inner HDI buried hole is not filled with resin, the PCB board will explode when overheated and will be directly scrapped. If resin plug holes are not used, multiple sheets of PP are required to be pressed together to meet the filling requirements. However, the thickness of the dielectric layer between the layers will be thicker due to the increase of the PP sheet.
AOI Inspection of PCBPCB Automated optical inspection (AOI) is an automated visual inspection of Printed Circuit Board manufacturer where a camera autonomously scans the device under test for both catastrophic failure (such as missing component) and quality defects. It is commonly used in the Multilayer PCB manufacturing process because it is a non-contact test method. It guarantees the high reliability of Multi-CB multilayer circuit boards. Depending on its visual methods, the AOI test can be used to detect a lot of surface defects for the Multilayer PCB, such as opens, shorts, incorrect components, missing components, etc.
Final Quality Inspection of PCBZero defect is our goal during the PCB manufacturing process, all our products for PCB,100% test and inspection, acceptance standard IPC-A-600-H and IPC-6012;100% Double Inspection before outgoing.
CNC Routing of PCB CNC machine prototyping can provide a fast-turnaround board production process without the need for wet processing. If a CNC machine is already used for drilling, this single machine could carry out both parts of the process, drilling, and milling. A CNC machine is used to process drilling, milling, and cutting.Many boards that are simple for milling would be very difficult to process by wet etching and manual drilling afterward in a laboratory environment without using top of the line systems that usually cost multiple times more than CNC milling machines.
PTH of PCBThe copper foil of the double-sided or multi-layer composite board is originally an insulating layer. Sometimes in order to achieve certain required functions, the connection and conduction between the layers are required. On the non-conductive hole wall substrate that has been drilled, chemical The method deposits a thin layer of chemical copper as the base for electroplating copper later. At this time, it is necessary to plate through holes on the copper foil, namely PTH (Plating Throught Hole).
Etching of PCB The electronic test for circuit boards is performed after manufactured. All the PCB manufactured by PCBWay must be checked with flying probe test.The layout is analysed according to the PCB file for short circuits and interruptions.This is important because only the E-test detects incorrect and broken conductors. And the detected defective circuit board will be rejected or marked.It is a common mistake that a once free of errors produced circuit board no longer needs to be tested by the E-test. However, because each production batch of a circuit board is a one-time process, the E-Test has to be conducted each time.
Exposure of PCBThe purpose of the circuit board exposure: through ultraviolet light irradiation and phenanthrene block, the transparent place of the film and the dry film undergo optical polymerization reaction, that is, under ultraviolet light irradiation, the photoinitiator absorbs the light energy and decomposes into free radicals, and the free radicals initiate light again The polymerized monomer undergoes polymerization and cross-linking reaction, and forms a macromolecular structure insoluble in dilute alkali solution after the reaction.
