1356004 九、發明說明： 【發明所屬之技術領域】 本發明涉及一種平面構件之結構化黏合方法。本發明特 別是提供一種方法’其允許快速、成本有利地且以已界定 的黏合接縫來黏合已結構化的構件。 【先前技術】 有各種不同的方法使二個或多個物體黏合至一構件上。 主要步驟是施加一黏合劑到至少一即將黏合的區域，確定 接近此物體以及固定此物體以使黏合劑在附近位置中硬 化。 a)施加一黏合劑 有各種不同的方法可施加一黏合劑。最爲人所知者是針 頭分配法（所謂噴墨壓印法）以及所謂絲網印刷法。 在針頭分配法中’一種針頭以小的間距（大約1 〇 〇微米） 在待黏合的表面上運行且黏合劑經由針頭而壓印在表面 上。此方式具有重大的缺點，即：其是一種串列式的方法， 即’施加黏合劑有時很耗時。在數米長的黏合長度中，黏 合過程保持一段很長時間。在黏合長度大約3米時，黏合 過程例如介於1 0和20分鐘之間。本方法亦可以多個針頭來 同時進行。當然，此種以一針頭來進行的分配法在維護上 較昂貴，在以多個針頭來進行時不經濟。 當不夠快速時~種較快速的解法是藉由噴墨法來施加黏 合劑。3米長的黏合長度此處可在5至10分鐘之內施加完 成。因此’此種施加過程是藉由小滴方式施加而成。這樣 1356004 會造成二種困難處》—方面是要製成體積小於10 nl之小滴 時在技術上較困難且昂貴。黏合軌跡之細微度因此是有限 的’此時不須試圖達成一種在技術上較高的耗費。另—方 面由於在多個小滴一起流動時此施加過程已分成一定份量 來進行而會造成通常並不平滑的線條，這樣會使此方法不 適用於某些應用中。 絲網印刷法是一種將黏合材料施加至可黏合的表面上所 用的習知方法。於此’以一種絲網（例如，紡織物）作爲遮罩 鲁 且黏合材料經由此織物而塗佈在待黏合之物體之表面上。 此時出現的問題是：使用一種具有聚合物之黏合材料成份 時，實際上通常會使絲網印刷時所用的織物被黏合著且因 此會造成阻塞現象。由於黏合材料發生部份硬化（即，聚合） 現象或溶劑已在絲網上發生蒸發現象，則在網上會形成沈 積物使織物之網被阻塞。這樣又會使黏合材料不能完整地 被塗佈著。於是，硏究一種似水的黏合材料來克服上述問 題，這例如已描述在EP 0 866 840中。當然，即將使用之 ® 黏合材料通常都已確定，因此不能輕易地轉用其它的黏合 材料。 b)確定接近該物體 已確定的黏合過程之下一步驟是以確定的方式來接近該 待黏合的物體。在某些應用中若只爲了使一物體固定至另 一物體，則在其它應用中-且特別是當涉及光學構件時須使 一物體準確地定位至另一物體上。此處，所謂定位可以是 二物體相互之間在黏合過程結束之後的相對定向，對準以 1356004 及界定距離。顯然，在大部份情況下（即’黏合劑可展現其 黏合作用時），黏合劑至少在待黏合的各面之間之一區域中 * 佔有一種厚度（亦可能是最小厚度）。但此厚度通常由該應用 過程來設定。即，吾人例如以一種固定之2微米、5微米或 10微米之黏合接縫來進行黏合。 爲了達成上述固定的黏合接縫，則各物體首先須以確定 方式互相接近。然而，大部份情況下且特別是面積較大時， 需發出一種壓力，特別是當此接近過程以較快的速率來進 ® 行時。當然，光學組件中各組件的抓握及其平移操作通常 會發生問題。藉由工具以使用機械壓力時會對光學表面造 成間接的損害。在某些情況下，使用毛細力及/或重力以進 行上述之接近過程。當然，此接近過程是費時的且昂貴。 因此，須尋求一種方法，其允許各物體以很小心但較以 毛細力或重力來進行時還快速的方式以成功地互相接近。 c)以固定間距來進行的硬化過程 爲了達成上述已界定的黏合接縫，則該接近過程應可以 ® 確定的方式來停止。此外，大部份的情況下都需要在硬化 期間使各物體保持在一已確定的間距處，然後一方面繼續 進行此硬化過程且另一方面多種黏合材料顯示其在硬化期 間可改變其固有體積之特性。爲了在硬化期間達成—種確 定的間距，則可有各種不同的方法。一方面是可在一個或 多個待黏合的物體上設置所謂間距支件（固定間隔元件）。然 後，黏合劑不施加在間距支件上，但在聚集各物體時，各 物體在間距支件上相接觸且界定了黏合接縫之厚度。當 1356004 . 然，此過程中施加上述已界定的間距支件至一物體上時需 要額外費用，這樣會使此過程較昂貴。 * 其它可能方式是在黏合劑中設置所謂間距支件-小球 (Spacer balls)。這些具有確定之厚度的間距支件-小球直接 混合至黏合劑中且與黏合劑一起施加至待黏合的面上。然 後，當二個物體互相擠壓時，此二個物體互相接近至一種 與間距支件-小球之直徑相等的距離處。若不使用球形的間 距支件（例如，間距支件-小球），則當然亦可使用其它幾何 • 形式的小球。由·於此一原因，間距支件-小球以下稱爲中性 之間隔元件（spacer)。在針頭分配時的情況下或藉由噴墨方 法來黏合時的情況下，上述混合至黏合劑中的間隔物顯示 出一種重大的問題，此乃因針頭或通道即將發生阻塞的危 險所造成8 因此，須尋求一種可用的方法，其允許使用上述之間隔 元件而不會造成上述之阻塞問題。 【發明內容】 ® 本發明的目的因此是提供一種黏合方法，其至少可克服 上述習知技術上的問題。 本發明的解法 本發明的解法是轉向至一種方法，此方法在專業領域上 構成習知之絲網印刷法。此方法的一種修正（modific;atiQn) 是將數微米的微粒混合至黏合物質中。硏究結果已顯示： 織物已令人驚異地不會完全阻塞而是可使絲網印刷過程獲 得大大地改良。此絲網印刷方法可使用黏合材料來實現而 Ι3$6〇〇4 無問題，即，不會發生上述之阻塞問題。 本發明的其它特點是：可選取上述已混合的微粒的大 小，使其在黏合材料層中用作間隔元件。因此，不只可提 供〜種已改良的絲網印刷方法，且同時亦可將一種保持著 該黏合接縫之厚度所需的主要標記混合至該黏合劑中。在 以下的說明中，已混合的微粒在此種情況下亦稱爲”間隔元 件”，這些微粒不應明確地限定該黏合接縫之厚度。 本發明的另一.特點是提供一種方法以使二個即將黏合的 物體加速地接近。若各物體中之一包括多個直通至即將黏 合於其上的另一物體的孔或洞，則外部區域（物體之一應在 此外部區域上緊靠另一物體）可由外部來密封且各孔及/或 各洞被抽成真空。藉由環境大氣壓力使其中一物體對著另 一物體而受到擠壓。這以有規律的方式進行且其它機械工 具不必施加在待黏合的物體上。 本發明以下將藉由不同的實施形式及圖式來詳述。 【實施方式】 四種要素對絲網印刷方法具有決定性的影響：印刷媒 體，具有藥膜區（用來界定即將壓印的結構）之絲網，基板之 表面（其上應進行壓印）以及橡皮刮板，其藉由絲網而壓在印 刷媒體上。 第1圖顯示絲網印刷裝置1之組成要素之圖解。絲網3 包含藥膜區5，其在織物上確定一些區域，這些區域不能透 過該印刷媒體。於此，最後須界定該即將壓印在基板表面 上的結構。例如，使用一種60x60公分之正方形框架，但 1356004 · 亦可使用較大或較小的框架。然後，無干擾性的可壓印面 最後佔有此框架大小之三分之二。絲網藉由一種例如由鋁 所構成的框架來撐開。聚脂織物或其它紡織纖維織物或鋼 網（較佳是由不銹鋼所構成）適合用作絲網材料。本說明書中 織物之槪念須簡要而清楚地說明了絲網之全部的實施形 式，即，鋼網和其它之柵格。構成織物所用的要素通常稱 爲”絲線”。絲網具有一種此過程中已確定的網眼大小。絲 線周期依據使用情況典型値是由60微米至300微米。例如， 選取一種絲線周期是100x 1 00平方微米之聚脂織物，絲線直 徑大約是40微米。當然，亦可有利地使用絲線直徑介於30 微米和200微米之間的其它絲線，其中絲線直徑當然應較 織物之絲線周期小很多。絲線的厚度大體上決定了印刷媒 體之傳送至表面上的材料之厚度。 爲了對絲網3進行遮罩，則須在絲網上以大面積方式塗 佈一種光敏藥膜且經由光罩來對此藥膜進行曝光。藥膜例 如可以是一種正性光漆或亦可以是一負性光漆。在正性光 漆之情況下，在顯像之後會留下一些區域，這些區域在多 個經由光罩所曝光的區域被剝除期間未曝光。在負性光漆 之情況下，上述情況恰巧相反。結果，在上述二種情況下， 可保留一種織物，其含有以藥膜來密封的多個區域，印刷 媒體可未經由這些區域而受到擠壓。反之，印刷媒體可經 由無藥膜之區域而侵入。藥膜對施加在即將壓印的基板之 表面上的媒體之厚度具有影響性。藉由藥膜，則厚度可增 加50%。藉由上述方法可製成各種結構，其最小之組成要素 1356004 可以是所使用的絲網之網眼大小的3倍。在結構 網眼至少在多種應用中會對印刷圖像造成干擾。 本發明中一種以間隔元件來混合的環氧樹脂黏 合用作印刷媒體9。但此種黏合材料成份亦可以是 外線來硬化-、熱硬化或由多個成份以化學方式 或藉由溶劑之稀釋來硬化之黏合材料。例如，可 是5微米的玻璃球。可合理地使用其它値（其大小 到網眼開口之80%)。但間隔元件之最大尺寸較佳 由網眼所定義的間隙之最小尺寸的30%。在詢問” 濃度之間隔元件來進行混合”時，須注意：太高的 -濃度會使間隔元件結塊且因此會使織物阻塞。有· 是在0.5 %至80 %之間。在間距支件-小球的情況下 佳値是5 %。 爲了進行絲網印刷方法，框架7中所展開的絲 在基板1 3之待印刷的表面上大約5至1 〇公分處。 網3對準基板1 3，則一種相機須運行至基板1 3和 間（圖中未顯示）且例如藉由一種劃分稜鏡配置來 網3之相對於基板1 3之位置且情況需要時進行修 進行對準之後，移除該相機且將該絲網運行至 0.5mm和5mm之間的距離處，較佳是運行至2mm 然後，已與間隔元件相混合之黏合材料（較佳是: 施加至絲網3上以作爲印刷媒體9。然後，藉由 1 1以一種壓力而越過織物且因此使黏合材料和其 的間隔元件一起受到該織物所擠壓。該壓力須選 較小時， 合材料適 一種以紫 來硬化-、 使用直徑 大約可達 是不超過 應以何種 間隔元件 利的濃度 濃度之較 網3配置 爲了使絲 絲網3之 控制此絲 正。在已

5來結構化時的印刷情況，橡皮刮板已經由這些區域離 開。 就上述方式而言，就像橡皮刮板經由織物而運行一樣， 有各種不同的配套方式。典型方式是使橡皮刮板經由織物 運行一次即已足夠。但雙橡皮刮板-技術亦可行，其中橡皮 刮板進行一種來/回移動。 在將一已結構化的黏合膜施加在一物體的表面上之後， 二個即將黏合的表面須互相接近。若一表面須被結構化以 進行黏合，則此行.的專家通常須準確地實現已界定的黏合

Description of the Invention: [Technical Field] The present invention relates to a structured bonding method for a planar member. In particular, the present invention provides a method which allows for fast, cost-effective and bonded bonding of structured components with defined adhesive seams. [Prior Art] There are various ways to bond two or more objects to a member. The main step is to apply an adhesive to at least one area to be bonded, to determine access to the object and to secure the object to harden the adhesive in a nearby location. a) Applying an adhesive There are various ways to apply a binder. The best known are the needle dispensing method (so-called inkjet imprinting) and the so-called screen printing method. In the needle dispensing method, a needle runs on a surface to be bonded at a small pitch (about 1 〇 〇 micrometer) and the adhesive is embossed on the surface via a needle. This approach has the major drawback that it is a tandem method, i.e. 'application of adhesives can sometimes be time consuming. In a few meters long bond length, the bonding process is maintained for a long time. When the bonding length is about 3 meters, the bonding process is, for example, between 10 and 20 minutes. The method can also be performed simultaneously with a plurality of needles. Of course, such a dispensing method with one needle is expensive to maintain and uneconomical when using multiple needles. When it is not fast enough, a faster solution is to apply the adhesive by an inkjet method. The 3 m long bond length can be applied here within 5 to 10 minutes. Therefore, this application process is applied by droplets. Thus, 1356004 would cause two difficulties. The aspect is that it is technically difficult and expensive to make droplets smaller than 10 nl. The nuance of the bond trajectory is therefore limited. There is no need to attempt to achieve a technically high cost. On the other hand, since the application process is divided into a certain amount when a plurality of droplets flow together, a line which is usually not smooth is caused, which makes the method unsuitable for some applications. Screen printing is a conventional method used to apply an adhesive to a bondable surface. Here, a screen (e.g., a woven fabric) is used as a mask and the adhesive material is applied to the surface of the object to be bonded via the fabric. The problem that arises at this time is that when a polymer-bonded component is used, the fabric used in the screen printing is usually bonded and thus causes clogging. Due to partial hardening (i.e., polymerization) of the bonding material or evaporation of the solvent on the screen, deposits are formed on the web to cause the fabric web to become clogged. This in turn will prevent the adhesive material from being completely coated. Thus, a water-like adhesive material is sought to overcome the above problems, which is described, for example, in EP 0 866 840. Of course, the ® adhesives that will be used are usually identified and cannot be easily transferred to other adhesives. b) Determining the proximity of the object A step under the determined bonding process is to approach the object to be bonded in a defined manner. In some applications, in order to secure an object to another object, in other applications - and particularly when it comes to optical components - an object must be accurately positioned onto another object. Here, the positioning may be the relative orientation of the two objects after the end of the bonding process, aligned at 1356004 and defining the distance. Obviously, in most cases (i.e., when the adhesive exhibits its adhesion), the adhesive occupies at least one thickness (and possibly the minimum thickness) in at least one region between the faces to be bonded. However, this thickness is usually set by the application process. That is, the adhesive is bonded, for example, by a fixed 2 micron, 5 micron or 10 micron adhesive joint. In order to achieve the above fixed adhesive seam, the objects must first approach each other in a defined manner. However, in most cases, and especially when the area is large, a pressure is required, especially when the approaching process enters the line at a faster rate. Of course, the gripping of the components of the optical assembly and its translational operation often cause problems. Indirect damage to the optical surface is caused by the use of mechanical pressure by the tool. In some cases, capillary forces and/or gravity are used to perform the proximity process described above. Of course, this approaching process is time consuming and expensive. Therefore, a method has to be sought which allows objects to be successfully approached to each other in a manner that is very careful but also faster than capillary force or gravity. c) Hardening process at regular intervals In order to achieve the above defined bonded joints, the approaching process should be stopped in a defined manner. In addition, in most cases it is necessary to keep the objects at a certain distance during hardening, and then continue the hardening process on the one hand and on the other hand the various adhesive materials show that they can change their inherent volume during hardening. Characteristics. In order to achieve a defined spacing during hardening, there are a variety of different methods. On the one hand, so-called pitch supports (fixed spacer elements) can be provided on one or more objects to be bonded. Then, the adhesive is not applied to the spacers, but when the objects are gathered, the objects contact the spacers and define the thickness of the bonded seams. When 1356004. However, the above-mentioned defined spacing support is applied to an object during this process at an additional cost, which makes the process more expensive. * Other possible ways are to set up so-called spacers - Spacer balls in the adhesive. These spacers having a defined thickness - the pellets are directly mixed into the binder and applied to the face to be bonded together with the binder. Then, when the two objects are pressed against each other, the two objects approach each other to a distance equal to the diameter of the pitch support-ball. If spherical spacers (for example, pitch supports - small balls) are not used, it is of course also possible to use balls of other geometric forms. For this reason, the pitch support - the small ball is hereinafter referred to as a neutral spacer. In the case of needle dispensing or when bonded by an ink jet method, the above-described spacers mixed into the adhesive exhibit a significant problem due to the risk of impending clogging of the needle or channel. Therefore, a method is available that allows the use of the spacer elements described above without causing the aforementioned blocking problems. SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a bonding method which overcomes at least the above-mentioned problems of the prior art. Solution of the Invention The solution of the present invention is directed to a method which constitutes a conventional screen printing method in the professional field. A modification of this method (modific; atiQn) is to mix several micron particles into a binder. The results of the study have shown that the fabric has surprisingly not completely blocked but allows the screen printing process to be greatly improved. This screen printing method can be realized using an adhesive material and Ι3$6〇〇4 is no problem, that is, the above blocking problem does not occur. Another feature of the invention is that the size of the above-described mixed particles can be selected to be used as a spacer element in the layer of adhesive material. Therefore, not only can an improved screen printing method be provided, but also a main mark required to maintain the thickness of the bonded seam can be mixed into the adhesive. In the following description, the mixed particles are also referred to as "spacers" in this case, and these particles should not explicitly define the thickness of the bonded seam. Another feature of the invention is to provide a method for accelerating the proximity of two objects to be bonded. If one of the objects includes a plurality of holes or holes that pass through to another object to be bonded thereto, the outer region (one of the objects should abut against the other object on the outer region) can be sealed from the outside and each The holes and/or holes are evacuated. One of the objects is squeezed against another object by ambient atmospheric pressure. This is done in a regular manner and other mechanical tools do not have to be applied to the object to be bonded. The invention will be described in detail below by means of different embodiments and figures. [Embodiment] The four elements have a decisive influence on the screen printing method: a printing medium having a film area (to define a structure to be imprinted), a surface of the substrate (on which embossing should be performed), and A squeegee that is pressed against a print medium by a screen. Fig. 1 is a view showing the components of the screen printing apparatus 1. The screen 3 contains a film area 5 which defines areas on the fabric which are not permeable to the print medium. Here, the structure to be imprinted on the surface of the substrate must be defined at the end. For example, use a 60x60 cm square frame, but 1356004 · Larger or smaller frames can also be used. Then, the non-intrusive embossable surface finally occupies two-thirds of the size of the frame. The screen is stretched by a frame, for example made of aluminum. Polyester fabric or other woven fabric or stencil (preferably composed of stainless steel) is suitable for use as the screen material. The mourning of the fabric in this specification requires a brief and clear description of all embodiments of the screen, i.e., stencils and other grids. The elements used to make up the fabric are often referred to as "filaments." The screen has a mesh size that has been determined in this process. The wire cycle is typically from 60 microns to 300 microns depending on the application. For example, a polyester fabric having a thread cycle of 100 x 100 square micrometers is selected, and the wire diameter is about 40 micrometers. Of course, it is also advantageous to use other wires having a wire diameter between 30 microns and 200 microns, wherein the wire diameter should of course be much smaller than the wire period of the fabric. The thickness of the wire generally determines the thickness of the material delivered to the surface by the printing medium. In order to mask the screen 3, a photosensitive film must be coated on the screen in a large area and exposed through a mask. The film may be, for example, a positive varnish or a negative varnish. In the case of a positive lacquer, areas are left after development that are not exposed during the stripping of multiple areas exposed through the reticle. In the case of negative varnish, the above situation happens to be the opposite. As a result, in both of the above cases, a fabric can be retained which contains a plurality of regions sealed with a film through which the printing medium can be not pressed. Conversely, the print medium can be invaded through the area of the film-free film. The film has an effect on the thickness of the medium applied to the surface of the substrate to be imprinted. With the film, the thickness can be increased by 50%. Various structures can be produced by the above method, and the smallest component 1356004 can be three times the mesh size of the screen used. In the case of structural meshes, at least in a variety of applications, the printed image may be disturbed. In the present invention, an epoxy resin mixed by a spacer member is used as the printing medium 9. However, the composition of the adhesive material may also be an external wire for hardening - heat hardening or an adhesive material which is hardened by chemically or by dilution of a plurality of components. For example, it is a 5 micron glass sphere. Other flaws (the size of which is 80% of the mesh opening) can be reasonably used. However, the largest dimension of the spacer element is preferably 30% of the minimum dimension of the gap defined by the mesh. When interrogating the "interval components of the concentration for mixing", it is important to note that too high a concentration will cause the spacer elements to agglomerate and thus block the fabric. Yes, it is between 0.5% and 80%. In the case of a pitch support - a small ball, the best is 5%. For the screen printing method, the filaments unfolded in the frame 7 are on the surface of the substrate 13 to be printed about 5 to 1 cm. The mesh 3 is aligned with the substrate 13 and a camera must be run to the substrate 13 and between (not shown) and the position of the mesh 3 relative to the substrate 13 is configured, for example, by a split 稜鏡 configuration and the situation is performed as needed After the alignment is performed, the camera is removed and the screen is run to a distance between 0.5 mm and 5 mm, preferably to 2 mm, and then the bonding material has been mixed with the spacer elements (preferably: applied To the screen 3 as a printing medium 9. Then, the fabric is passed over the fabric by a pressure of 1 1 and thus the bonding material and its spacer elements are pressed together by the fabric. The material is suitable for hardening with purple - the diameter can be up to no more than the spacing concentration of the element should be compared with the net 3 configuration in order to make the wire mesh 3 control this wire positive. Epoxide) The mixture in the squeegee is selected to be sufficient -11 - 1356004 high > so that the fabric can be placed at this position (the squeegee is in contact with the fabric at this position, as shown in Figure 2) Pressed underneath to be printed Surface. Typical pressure enthalpy is varied in the range of 〇.2N/cm. Here, the expression "how much force per centimeter" is used, because the squeegee is usually a scraper-like item. Fig. 2 shows the printing of some areas of the substrate 13 with the adhesive film 15 structured, and the squeegee has been separated from these areas. In the above manner, just as the squeegee runs through the fabric, there are various ways of matching. Typically, it is sufficient to run the squeegee once through the fabric. However, the double squeegee-technology can also be used, in which the squeegee performs a kind of movement/return. After applying a structured adhesive film to the surface of an object, the two surfaces to be bonded must be close to each other. If a surface has to be structured for bonding, experts in this line must generally accurately define the defined bond joint. This means that the width and thickness of the adhesive layer must be defined. In addition, it is necessary to prevent the formation of bubble impurities during optical applications. The bubble impurities are usually formed by the screen printing method itself and the conditions when the two objects approach. As the inventors have determined, the bubble impurities cannot be heated only to 30.080 by applying the adhesive film. C (preferably 60. C) is to be prevented from satisfying other conditions, that is, the ratio of the applied film width to the applied film thickness cannot be more than 20:16 in at least one dimension, that is, it must be coated very much. Long strips 'as long as the width of the strip does not exceed 20 times the thickness of the strip. The heating of the adhesive material causes a jet of air bubbles due to surface tension. In addition, the selection of the geometry in the above-mentioned dimension results in a convex -12- 1356004. The product, at this time, is substantially free of bubble impurities when the second object to be bonded is applied. Now, if the two objects are squeezed close to each other in a precisely defined manner, the two objects approach each other until the spacing elements prevent further access. As stated, this distance can be 5 microns. Of course, it is important to note during the above approach: if one has been issued then this pressure should be emitted as evenly as possible. If dense objects with optical surfaces should be bonded to each other, in many cases it is not possible to simply transfer the pressure to the object to be bonded. For this reason, another feature of the invention is to provide a method which allows the two objects to approach each other. This method is feasible in "only one of the two objects is made such that a more evenly distributed channel allows access to the g of the other object. Figure 3 shows the configuration required for this method to proceed. The structured object 1 〇 5 of the material film 1 依据 3 is placed on an adhesive support 107. This adhesive support is provided with a plurality of which are selectively connected to the pressure pump via a valve or a vacuum pump® 'The pressure pump is used to generate a gas flow. Then, the body to be bonded is approached to the film of the adhesive material. By the air flow to produce a second object, it can be left in contact with the air cushion without contact. Usually, the so-called (Bernoulli) The effect is effective here. Now, if the airflow is slow to zero, then the second object descends in a defined manner until the first object channel is now sealed against the ring by the adhesive film and the second object Π 0. Then 'Each channel is connected to the vacuum pump. Now, if the true valve is open', then the air is pumped out by the channel and a kind of owing will produce a mutual contact with the above pressure. The optical fine is made by the tool. Advantageously, the structured E-face" is in the form of the invention and is channeled. The first second air cushion, Bo tried to slow down.
