The MLCC is formed by stacking ceramic dielectric films with surface printed electrodes (internal electrodes) in an interleaved manner, sintering at high temperature to form a ceramic block, and then sealing a metal layer (external electrode) at both ends of the ceramic block. When preparing the MLCC, the following processes are generally performed: batching, casting, printing, layering, laminating, cutting, degassing, sintering, chamfering, end sealing, end burning, and plating. The MLCC must be processed by the plating process, and various metals such as nickel plating, tin plating, copper plating, gold plating, and silver plating are generally used. The thickness of the plating layer will affect the performance and cost of the product, and therefore, the thickness of the plating layer needs to be measured.

[0003] The conventional method is to measure the thickness of the plating layer after plating by using an instrument or a DPA method, and to determine the product quality and process adjustment according to the measured plating layer thickness. The thickness of the plating layer of the MLCC product is usually measured by using a fluorescent XRF thickness gauge. During the measurement, the samples are taken one by one by using tweezers and placed in the thickness gauge for measurement, and the measurement efficiency is low. CONTENT OF THE UTILITY MODEL

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] For the technical problems in the background art, the present application provides a MLCC product plating thickness sample preparation tool, such as Figure 1 In an embodiment, the MLCC product plating thickness sample preparation tool 100 includes a support plate 10, an adhesive member 20, and a sample preparation workpiece 30. The left side of the support plate 10 is a marking area 11, and the right side is a sample preparation area 12. The MLCC product plating thickness sample preparation tool 100 of the present application can be used to simultaneously perform thickness measurement on multiple groups of MLCC products to be measured, and therefore multiple sets of sample marks are provided from top to bottom in the marking area 11. Specifically, the sample marks can be printed or pasted on the support plate 10.

[0033] The adhesive member 20 and the sample preparation workpiece 30 are both provided in the sample preparation area 12. The sample preparation workpiece 30 can be fixed to the sample preparation area 12 by the adhesive member 20, or it can be fixed to the sample preparation area 12 by other detachable connection methods.

[0034] In the present embodiment, the sample preparation workpiece 30 corresponds to the multiple product marks of the marking area 11, and multiple sample preparation areas 31 are provided from top to bottom. For each sample preparation area 31, it includes multiple through holes 35, and the bottom of the through hole 35 is connected to the adhesive member 20.

[0035] In the present embodiment, the size of the through hole 35 is slightly larger than the MLCC product to be measured, so that a single MLCC product to be measured can enter the through hole 35 when the support plate 10 is shaken, and be adhered by the adhesive member 20 at the bottom of the through hole 35.

[0036] The working process of the MLCC product coating thickness measurement sample preparation tooling 100 in this embodiment is as follows:

[0037] First step: Sequentially set the attachment 20 and the sample preparation workpiece 30 in the sample preparation area 12 of the support plate 10, and configure multiple groups of sample identifiers in the identifier area 11 of the support plate 10;

[0039] Third step: Shake the support plate 10 so that the MLCC products in the sample preparation sub - area 31 enter the through holes 35 and are adhered by the attachment 20;

[0040] Fourth step: If there is no MLCC product entering a through hole 35, shake it again or manually ensure that each through hole 35 has an MLCC product entering, and pour out the MLCC products in the sample preparation sub - area 31 that did not enter the through holes 35;

[0041] Fifth step: Remove the sample preparation workpiece 30, and put the MLCC product coating thickness measurement sample including the support plate 10 together with the MLCC samples adhered to the attachment 20 into the thickness gauge for detection in sequence;

[0042] Sixth step: Preserve the MLCC product coating thickness measurement sample and the support plate 10 for traceability and re - inspection.

[0043] The MLCC product coating thickness measurement sample preparation tooling in the embodiment of this application can simultaneously shake multiple groups of MLCC product samples into the through holes reserved by the sample preparation workpiece, greatly improving the sample preparation efficiency; the sample information corresponds to each sample, effectively preventing the occurrence of material mixing errors; after the MLCC product samples enter the through holes and are adhered, the sample preparation workpiece can be disassembled from the support plate and reused for the next support plate, saving materials; the measured samples do not need to be removed from the support plate, and the support plate and the samples are stored together, facilitating subsequent result traceability and sample re - inspection.

The adjacent partitions 34 or the partitions 34 and the short sides of the frame 33 enclose a sample preparation area 31 that corresponds one-to-one with the multiple sets of sample labels arranged vertically. An opening is formed on the right side of the sample preparation area 31.

[0046] In this embodiment, the remaining sample in the sample preparation area 31 can be poured out from the opening on the right.

[0047] Preferably, the sample workpiece 30 is also disposed on the adhesive attachment 20, that is, the base plate 32 is also disposed on the adhesive attachment 20.

[0048] In a preferred embodiment, the adhesive attachment 20 is double-sided tape, and the sample workpiece 30 is fixed to the sample preparation area 12 by adhering its base plate 32 to the double-sided tape.

[0049] exist Figure 1 In one embodiment, the number of through holes in each group is 10; in other embodiments, the number of through holes can be 5-30. Preferably, the through holes 35 are arranged laterally between two adjacent partitions 34, so that the sample preparation workpiece 30 can load as many groups of MLCC test samples as possible.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims, and the specification can be used to interpret the content of the claims.
