Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] The invention provides a method for testing the uniformity of a Plasma machine, and the method for testing the uniformity of a Plasma machine specifically includes the following steps:

[0033] Step 1. Prepare several test pieces 10, bake the test pieces 10 at 135°C for 30 minutes, put them into a drying dish and cool them to room temperature, weigh and mark the cooled test pieces 10;

[0034] Step 2: Prepare three sets of copper-clad fixture boards 20 and several copper-clad dummy boards 30, respectively put the test piece 10 into the finished copper-clad fixture board 20, and fix the four corners of the test piece 10 with high-temperature adhesive tape. In this embodiment, 9 PCS test pieces 10 are mounted on each copper-clad fixture board ...

Abstract

The invention relates to a Plasma machine uniformity test method, which comprises: 1, preparing a plurality of test pieces, baking the test pieces, placing the baked test pieces in a drying dish, cooling to a normal temperature, weighing, and marking; 2, respectively putting the test pieces into a copper-clad jig plate; 3, putting the copper-clad jig plate and the plurality of copper-clad dummy plates into a Plasma machine according to a certain rule; 4, carrying out Plasma test; 5, after the Plasma is finished, detaching the test pieces from the interior of the copper-clad jig plate, then baking the test pieces, then putting the test pieces into a drying vessel to be cooled to the normal temperature, and then weighing the test pieces; and 6, calculating results, wherein the test results of the nine areas are qualified only when the percentages of the test results are greater than or equal to 70%. According to the invention, the uniformity of the whole Plasma machine and the stability during product production are comprehensively evaluated and monitored, so that stable performance and stable product quality when the Plasma machine is put into mass production can be ensured.

Description

technical field [0001] The invention relates to a test method, in particular to a Plasma machine uniformity test method. Background technique [0002] Plasma degumming is very important in the circuit board industry. For high Tg halogen-free boards, if there is no plasma degumming process, the problem of IP separation will occur. Therefore, how to evaluate the performance of the Plasma machine and how to establish a systematic monitoring method to confirm the test effect after Plasma are the most important. However, at present, many PCB factories do not have a unified plasma test method when doing plasma deglue plasma, and cannot evaluate whether the plasma machine can meet the relevant requirements and whether the products after plasma can meet the requirements for the production of the most difficult production boards. Contents of the invention [0003] For this reason, the object of the present invention is to provide a kind of Plasma machine uniformity testing method,...
