12 Exit Criteria for Finished Membrane Switches in JRPanel

 At JRPanel, we are obliged to bring the highest quality membrane switch panel products to our customers. 


In addition to selecting the highest quality raw materials, our engineers will conduct a final quality inspection on the products before packaging the finished products. So what criteria does JRPanel use to judge whether the membrane switch product meets the market standards? Today we will share with you 12 12 exit criteria in JRPanel.


Criterion 1


Open circuit, short circuit: 

No open or short circuit phenomenon in the conductor is allowed.


Criterion 2


Conductor: 

There must be no fingerprints or foreign objects on the circuit. The conductor should be uniform and smooth.


Criterion 3


Ink: 

Make sure that the ink completely covers the silver paste, and there should be no obvious protruding of the silver paste.


Criterion 4


Up and down circuit position offset: 

The allowable tolerance for the mutual offset of the center positions of the switch contacts of the upper and lower circuits is ±0.2mm.



Criterion 4


Criterion 5


Material: 

Substrate, silver paste, ink, interlayer, surface glue, back glue, reinforcement board, insulation printing should meet the requirements of the drawings.


Criterion 6


Shape: 

The shape, conductor circuit, insulation treatment, etc. should comply with the drawings and be consistent with the physical samples provided by the customer.


Criterion 7


Punching flash and die extrusion size: 

Punching flash and extrusion size should not be greater than 0.2mm.


Criterion 8


Switch contact point: 

No insulating ink , and the insulating ink surface should be flat, avoiding any defects such as bubbles or pinholes.


Criterion 8


Criterion 9


Defects such as burrs: 

There should be no residual material scraps, foreign bodies, stains, and burrs on the surface.


Criterion 10


Physical scratches and cuts: 

No scratches and cuts on the surface and the inside. The scratches are easy to stay on the surface of the carbon ink, but they cannot affect the circuit conduction.


Criterion 11


Insulation surface:

After the insulating ink has dried, put the other sides against each other, and after heavy pressing for 24 hours, make sure that the insulating surfaces do not touch each other.


Criterion 12


Jumpers: 

All jumpers are in accordance with the requirements of line conductors, and all jumper products must pass 100% open, short circuit and insulation resistance tests. At the same time, the insulation resistance should be greater than 500MΩ.

Brief Introduction to Flat Spiral Coil Inductors

  Hi guys! Today JRPanel would like to share a few points about Flat Spiral Coil  Inductors  with you. Basically, a flat coil inductor is an inductor wound with flat copper wire.  The picture below is the side view, we can see that each circle of copper wire is arranged very compact. Here are some of the application characteristics of flat coils : 1.  High current inductance 2.  Lowest DC resistance           3.  Can ensure smooth drop of current-resistant inductance 4.  Suitable for reflow SMT process 5.  Lead-free, RoHS compliant This pciture shows a flat coil product.  It is generally used in power supplies, personal computers and other handheld  electronic devices . Advantages of  F lat  C oil  I nductors are : 1.  Scientific and reasonable space design. 2.  Tight and flat between turns ensures the effective cross-sectional area of the wire, which greatly reduces the copper loss ...

The Main Use and Classification Methods of Transformer Bobbins

  Hi guys, this blog is still about   high frequency transformers .   JRPanel   would like to introduce you the main use of transformer bobbins and how we classify them.   In the pictures are the transformer bobbins.        Following are the main uses of that JRPanel has summarized for you:   1. The bobbins provide space for winding copper wires in transformers.   2. Wire channel in the bobbins provides path for transformer winding.   3. The bobbins help to fix the core in the transformers.   4. The metal pins in the bobbins are connected to the  PCB  after soldering, which play an important role in conducting electricity when the transformer is working.   5. The baffle at the bottom of the bobbins isolates the core from the tin stack to avoid poor volta ge resistance.       From this it can be seen that the importance of bobbins in transf...

7 Optimization Methods for Product Styling Design

JRPanel  has sorted out a series of styling design optimization strategies, hoping to help everyone think strategically in the innovative design stage. Product styling design optimization strateg ies: segmentation, cutting and stacking, bending and twisting, concave and convex treatment, spliting and connecting, folding, surface texture.  1. Segmentation A series of means to segment the form purposefully to achieve a certain functional effect. Segmentation includes the following three forms: functional segmentation, form segmentation, and compound segmentation. Function segmentation -the segmentation method to meet product production and practical functions; Formal segmentation -a segmentation method to satisfy the aesthetic system thinking of product modeling and color; Compound segmentation -a segmentation method that covers the above two effects. 2. Cutting and Stacking Cutting and stacking the shape to achieve a certain functional effect. 3. Bending and Twisting Bending an...
