Abstract
The invention relates to a manufacturing process for a high-frequency multilayer mixed compression signal plate. The prior multilayer mixed compression signal plate manufacturing process has complicated procedure, high production cost, low efficiency and energy wastage. The invention changes the compression process and the plated through hole (PTH) pretreatment process, wherein the compression process is changed as follows: typesetting is finished by two high-frequency plates and a common PP film and requires that the high-frequency plates finish compression after finishing etching; lamination is characterized in that typeset production plates are laminated into certain layers according to the production capacity of a press, and kraft paper comprises 10 pieces of old kraft paper and 10 pieces of new kraft paper; and compression is characterized by completing the finished structure of the product under high temperature and high pressure. The PTH pretreatment process is changed as follows: changing the polarity of teflon resin, inflating for 8min, desmearing for 15min, neutralizing for 5min, grinding the plates once, soaking in sodium naphthaline stock solution for 20min, and putting into a cylinder after carrying out secondary neutralizing. The invention realizes the mixed compression process of the high-frequency plate and the common PP, realizes the mass production of the mixed compression plate and reduces the production cost.
Description
Technical field
The present invention relates to the electronic circuit production field, be specifically related to a kind of manufacture craft of high-frequency multilayer mixed compression signal plate.
Background technology
The manufacture craft of existing multilayer mixed pressure signal plate comprises the heavy copper pre-treatment manufacture craft and the heavy copper pre-treatment manufacture craft of high frequency plate of common four layer signal plate pressings and manufacture craft, common four laminates.
Common four layer signal plate pressings and manufacture craft are:
I: after (by a core material, two films and two blocks of Copper Foils are accomplished) the common central layer etching of setting type to basic no requirement (NR) standing time.
II: lamination (output according to press is superimposed as certain number of plies with typesetted production plate)
Brown paper quantity is that 15 old+5 are new
III: pressing (under HTHP, accomplishing the finished product structure of product)
IV: the concrete parameter of pressing is following:
The heavy copper pre-treatment manufacture craft of common four laminates is:
Expansion (8min) → de-smear (15min) → neutralization (5min)
The heavy copper pre-treatment manufacture craft of high frequency plate is:
Mainly be the polarity that changes the Teflon resin, sodium naphthalene stoste is soaked (20min), from the back cylinder down that neutralizes.
Above-mentioned traditional handicraft exists shortcomings such as program complicacy, production cost is high, efficient is low, waste energy.
Summary of the invention
The object of the present invention is to provide a kind of manufacture craft of high-frequency multilayer mixed compression signal plate, reduce operation, promote quality; Raise the efficiency, energy savings reduces production costs; Can make conventional high frequency plate into 4 layers of designing requirement by two-sided according to the client,, realize the batch process of high-frequency multilayer mixed compression signal plate through the change of part of production; Make double sided board into four laminates, therefore solved the long-pending excessive problem of existing high frequency board assembly.
The present invention has changed process for pressing and heavy copper pre-treating technology on the basis of traditional processing technology, thereby guarantees production quality and volume production condition.
A: the change of process for pressing:
I: set type (central layer+1 common PP sheet by two high frequency plates is accomplished) requires high frequency plate central layer to accomplish after the etching and accomplished pressing at 8 hours
II: superimposed (output according to press is superimposed as certain number of plies with typesetted production plate) brown paper quantity is that 10 old+10 are new
III: pressing (under HTHP, accomplishing the finished product structure of product)
B: the change of heavy copper pre-treating technology:
Mainly be the polarity that changes the Teflon resin, concrete parameter is following:
Expansion (8min) → de-smear (15min) → neutralization (5min) →
Nog plate (once) → sodium naphthalene stoste is soaked (20min), from the back cylinder down that neutralizes.
The invention has the advantages that: A: through having changed process for pressing and heavy copper pre-treating technology, realized the mixed pressure technology of high frequency plate and common PP, finally realized the volume production of mixed pressure plate; B: the high-frequency signal of high-frequency multilayer mixed pressing plate can satisfy client's demanding terminal; C: energy savings, reduce production costs, be beneficial to popularization.
Embodiment
With most preferred embodiment the present invention is explained further details below:
The present invention has changed process for pressing and heavy copper pre-treating technology on the basis of traditional processing technology, thereby guarantees production quality and volume production condition.
A: the change of process for pressing:
I: set type (central layer+1 common PP sheet by two high frequency plates is accomplished) requires high frequency plate central layer to accomplish after the etching and accomplished pressing at 8 hours; Characteristics according to high frequency sheet material; Surface activity can fade away after 8 hours, so the long residence time to pressing after the etching was controlled within 8 hours.To guarantee the reliability of pressing.
II: superimposed (output according to press is superimposed as certain number of plies with typesetted production plate) brown paper quantity is that 10 old+10 are new, increases by 5 new brown paper, has played compensator or trimmer pressure to a certain extent, increases the mobile effect of film.
III: pressing (under HTHP, accomplishing the finished product structure of product)
The maximum difference of this program change is, the film flowability preferably the 3rd step of time period increased the time, make film obtain better filling.Increase the time at gel section 3-4 between step simultaneously, reduced certain heating rate, prolonged the gel time of film.
These two kinds of settings combine, and make our pressing stability and reliability obtain good guarantee.
