Precautions for mechanical drilling in circuit board factory

Circuit board manufacturer, circuit board designer and PCBA manufacturer explain the precautions for mechanical drilling of circuit board factory

PCBA processing is to connect various electronic components on PCB board through surface mount (SMT), plug-in (DIP) and other electronic assemblies. PCBA process flow mainly includes SMT, AOI, DIP, FCT testing and other processes. Due to the size difference of electronic components, there will be different processes and requirements in assembly and insertion. The assembly density of PCBA is relatively high, and the small size and light weight of electronic products also have certain changes and requirements in mounting. The reliability, seismic resistance and excellent weldability of the products have high requirements for the hardware and software facilities of PCBA processing.

What matters should we pay attention to when operating mechanical drilling in our circuit board factory? There is much knowledge in mechanical drilling. Follow the small editor to have a look!

Precautions for mechanical drilling in circuit board factory

First of all, our circuit board factory (Shenzhen circuit board) must wear gloves on the contact board (keep it clean, replace it regularly, and do not touch the board surface if there is dirt on the gloves).

Of course, the operators of our circuit board factory (Shenzhen circuit board factory) should hold the board naturally with both hands when taking the board, and remove the sundries on the table, base plate, cover plate and board before loading the board; The rough edges on the four shoulders of the cushion should be brushed clean by Jiao Wei; The used cover plate shall be free from wrinkles. These are to ensure that our circuit boards will not be scrapped or damaged after production.

When the personnel of our circuit board factory (Shenzhen circuit board factory) are pasting the adhesive tape, the adhesive tape cannot be stuck to the board surface, and the drill board must be transported with a plug-in frame; Pay attention not to scratch during production and transportation. What are the precautions for equipment operation?

During machine operation, all age protection devices must be in working condition; If the machine needs to be shut down for more than six hours, each drill shaft chuck must be loaded into the drill bit before shutting down, and the UP and DOWN values of the drill must be set reasonably, which cannot be too high or too low; Use adhesive tape to stick the four sides of the cover plate to the table, and the adhesive tape is stuck to the place where the width of the plate is about 1/3 of the width of the adhesive tape. If a broken tool is found in the drilling, first find out the spindle where the broken tool occurs and record it on the corresponding cover plate.

The circuit board manufacturer, circuit board designer and PCBA processor will explain the precautions for mechanical drilling of circuit board factory.
