Abstract
The invention relates to a control method of single-side mask opening hole and plumpness of hole clogging. The control method comprises the steps: S1 pre-processing: cleaning a board, removing the impurities and greasy dirt, and then performing sand blasting; S2 clogging holes by using aluminium sheets: according to the required aperture for hole clogging, selecting different bit diameter of the aluminium sheets to clogging the holes; S3 pre-baking: prebaking by placing a substrate in a tunnel baking oven, wherein the pre-baking temperature is 72-78DEG C and the baking time is 35-45min, and standing and cooling after baking; S4 using a film to perform hole position alignment, wherein the film is great than the holes to be clogged by 1-2mil; S5 developing: putting a circuit board in a developer to develop; S6 post-baking: backing the board in a plurality of segments; S7 grinding the board: conveying the circuit board to a non-woven board grinding device to grind the board, wherein the speed is 1.8-2.2m/min and the non-woven grinding roller speed is 200-500rpm; and S8 cleaning the surface: cleaning and drying the surface of the circuit board after board grinding, and then starting the resistance welding process. The control method of single-side mask opening hole and plumpness of hole clogging has the advantages of being high in the plumpness of hole clogging that the plumpness of hole clogging can reach 80% , and satisfying the production requirement for customers.
Description
Technical field
The present invention relates to wiring board production technology, particularly opening one side fenestra, consent plumpness control method.
Background technology
Printed wiring board, being called for short printed board, is one of vitals of electronics industry.Almost often kind of electronic equipment, little of electronic watch, calculator, arrive computer greatly, communication electronic device, military issue weapons system, as long as there are the electronic devices and components such as integrated circuit, in order to the electric interconnection between them, all will use printed board.In relatively large electronic product research process, the most basic success factor is the design of the printed board of this product, documentation and manufacture.The Design and manufacture quality of printed board directly has influence on quality and the cost of whole product, even causes the success or failure of commercial competition.
Via, in order to reach customer requirement, the necessary consent of via, and require higher to consent plumpness, but existing jack process often cannot meet the demand of client.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of opening one side fenestra, consent plumpness control method, consent plumpness is high, can reach more than 80%, meets the Production requirement of client.
Object of the present invention is achieved through the following technical solutions: opening one side fenestra, consent plumpness control method, comprise the following steps:
S1, pre-treatment: cleaning plate face, removing impurity greasy dirt, and ensure that plate face is dry, then carry out blasting treatment;
S2, aluminium flake consent: consent aperture as requested, select different aluminium flake brills to chew diameter and carry out consent:
When customer requirement consent different pore size size all appears in a model, an aluminium flake can be combined into by above condition; Consent just makes special aeroscopic plate or general-purpose aeroscopic plate+aluminium flake in process, consent scraper select the thick 45 DEG C of corner slickers of 20mm or 20mm thick, scraper angle 10-15 DEG C during consent, speed 1.5-2.5m/min, during silk-screen consent, plumpness will reach 110%, rabbet ink uses surface requirements color and does not add out profit, aluminium flake consent direction: 1. consent need be windowed from one side and be designed non-face consent of windowing; 2. two sides all has one side to window design, selects the face consent of windowing few; 3. negative and positive layout design consent is from component side consent;
S3, pre-baked: substrate is put into tunnel oven and carry out pre-baked, pre-baked temperature is 72 ~ 78 DEG C, and baking time is 35 ~ 45min, leave standstill cooling after coming out of the stove;
S4, hole point contraposition: use the film of the large 1 ~ 2mil of contrast boring ratio consent to carry out contraposition;
S5, development: wiring board is put into developing machine and develops;
S6, rear roasting: to adopt multistage to carry out baking sheet;
S7, nog plate: wiring board is sent in adhesive-bonded fabric Plate grinder and carry out nog plate, speed is 1.8 ~ 2.2m/min, and adhesive-bonded fabric roller speed is 200 ~ 500rpm;
S8, removing surface: cleaned in the wiring board plate face after nog plate, dry, enter welding resistance operation.
In described step S6, point three sections of baking sheets: first paragraph: baking sheet temperature is 58 ~ 62 DEG C, the baking sheet time is 15 ~ 25min; Second segment: baking sheet temperature is 78 ~ 82 DEG C, the baking sheet time is 15 ~ 25min; 3rd section: baking sheet temperature is 118 ~ 122 DEG C, the baking sheet time is 15 ~ 25min, and the total time of three sections of baking sheets is 60min.
In described step S8, also comprise the step of the wiring board of drying being carried out to QC inspection.
When described consent aperture is more than or equal to 0.65mm and is less than or equal to 0.8mm, use the aluminium flake that add little 0.1mm more overall than finished product aperture to bore and chew.
When described consent aperture is more than or equal to 0.45mm and is less than or equal to 0.6mm, the aluminium flake brill that diameter is 0.45mm is used to chew.
When described consent aperture is more than or equal to 0.25mm and is less than or equal to 0.4mm, the aluminium flake brill that diameter is 0.4mm is used to chew.
The present invention has the following advantages:
1, consent plumpness is high, can reach more than 80%, meets the Production requirement of client.
2, can solve and occur that the IC region half rabbet ink degree of depth is inadequate, client crosses in wave-soldering hole when at paster and produces gas backstreaming, IC is gone out the problem of specifying and pasting part position, can reduce gas backstreaming impulsive force when the degree of depth acquires a certain degree.
