Now when the customers carry out rigid flex pcb prototype, they always put forward higher requirements on the delivery date, the ability to handle complex samples and product quality of rigid flex pcb manufacturers, but because of each rigid flex pcb, the strength and equipment of manufacturers are not complete, resulting in the quality and price of the soft and tough combined board is also different. So, what's the usual work to do before rigid flex pcb prototype? Today we will take you to learn about it!

Note the number of prototypes

Figid flex pcb frequently needs production samples for testing before mass production,In fact, this part also occupied certain cost of rigid flex pcb manufacturers,In particular, the firm has large volume and there are numerous rigid flex pcb types produced,then rigid flex pcb prototype and testing cost are also extremely impressive,from this point of view,rigid flex pcb manufacturers should pay attention to the number of samples made during the proofing process.

Verify device packaging

It is a process in circuit board manufacturing process to weld a chip with a specific function and encapsulate it with a shield. In the production process of rigid flex pcb prototype, rigid flex pcb manufacturers should pay additional attention to whether the internal chips and electronic components are miswelded during packaging, so as to ensure the quality of rigid flex pcb prototype products, so as to verify the function properly and carry out additional large-scale production.

Do a thorough electrical check

After proofing, rigid flex pcb manufacturers should conduct comprehensive electrical inspection to ensure that rigid flex pcb can check every function and every detail. This is the significance of rigid flex pcb prototype and also the guarantee of whether the subsequent rigid flex pcb can be put into mass production and ensure a extremely low defect rate. Rigid flex pcb manufacturers need to do comprehensive electrical inspection and investigation. It is a more rigorous test.

There are some signal integrity layout and so on that need to be paid attention to and solved by both parties. But in general, rigid flex pcb prototype needs to pay attention to only the above problems. As a professional rigid flex pcb manufacturers, it is necessary to do a comprehensive investigation and test of the above problems, and it is the foundation to ensure rigid flex pcb product quality and transform into subsequent mass production.

Causes of short circuit in rigid flex pcb manufacturers?

The harm caused by short circuit to rigid flex pcb manufacturers is fairly great. The poor etching is an essential reason for rigid flex pcb short circuit. To find and improve the etching process to reduce the short circuit is rigid flex pcb manufacturers must go through the process, especially in the printed circuit board manufacturing process, etching process requirements are becoming more and more refined.

The harm caused by short circuit to rigid flex pcb manufacturers is fairly large, from burning components to scrapping pcb circuit board. Rigid flex pcb manufacturers only try to avoid short circuit, must grasp every step of production, check not let go of every suspicious point. In the etching process, normally causes circuit board short circuit, etching potion parameters improper control, the whole board electroplating copper plating thickness is not uniform, resulting in not complete etching.

Rigid flex pcb manufacturers short circuit improvement method

If the copper clad panel is scratched before storage, iqc must conduct spot inspection to check whether the panel surface is scratched or exposed on the substrate. If so, contact the supplier in time and deal with it appropriately according to the actual situation.

The copper-clad plate was scratched while cutting. The main reason is that there are tough sharp objects on the surface of the cutting machine. The friction between the copper clad plate and the sharp object causes the copper foil to be scratched, forming the phenomenon of exposed bottom. Before using materials, the table must be carefully cleaned to ensure that the table is flat and free of sharp objects.

When drilling, the copper coated panel was scratched by the drilling nozzle, the main reason is that the spindle clamp is wear or there is debris in the clamping nozzle is not cleaned, the length of the drilling nozzle is slightly longer than the set, the drilling height is not sufficient, and the employees of rigid flex pcb manufacturers scratched the copper foil at the tip of the drilling nozzle when setting the machine tool to move, forming the phenomenon of exposing the substrate.

Rigid flex pcb manufacturers staff in the transfer process caused the board scratch, because during the handling, the handling personnel lifted too numerous boards at a time, the weight was too large, the board did not lift during the handling, but was dragged up, resulting in friction between the board angle and the board surface, scratched the board surface; in addition, when putting down the board, because of the irregular place, in order to rearrange, with force to push the board, will also lead to friction between the board and scraping.

After heavy copper plating after laminated board cut caused by the improper operation, when the board after all sink copper plate electroplating deposit, because the boards are stacked together, when a certain amount of weight a lot, then down, voids, down a gravitational acceleration, form a powerful impact on the impact of the panel will lead to surface scratch, substrate.
