Specifically, the temperature of the solder is measured by flowing it through a reflow furnace while fixing the temperature measurement conducting wire of the reflow checker to the soldering location. Fixing of the conductive wire is performed by tape (having heat resistance) or soldering.

Then, when the temperature of the object reaches T3, the temperature in the furnace is lowered to gradually lower the temperature of the object. At this time, it is assumed that the temperature of T2 or higher is maintained for 30 seconds or more and 60 seconds or less in the object. Also, the temperature of the object is set to T3 at any timing during that period (soldering step). This melts the solder and then solidifies the molten solder.

Abstract
Description
また、特許文献1のような構成の場合、内部導体の接触ストロークを相手コネクタの内部に確保する必要がある。この場合も、コネクタ全体が大型化したりケースの内部の空間が狭小化したりする。
とは言え、基板コネクタを例えばリフローはんだ付け等で基板に表面実装した場合、防水性を担保するOリング等のシール部材が熱で損傷してしまい、シール部材が防水性を発揮しなくなる可能性がある。
すなわち、本発明の一態様に係るコネクタは、基板に実装されるコネクタであって、軸線方向に延びた筒状の外部導体と、前記外部導体の外周面に密着した状態で設けられた第1シール部材と、前記外部導体の内周面に密着した状態で設けられた第2シール部材と、前記外部導体の内側において前記軸線方向に沿って前記第2シール部材に挿入された内部導体と、を備え、前記第1シール部材及び前記第2シール部材は、前記基板に実装するときのリフローはんだ付けの温度に耐え得る耐熱性を有している。
第1シール部材及び第2シール部材の材料としては、ダウ・ケミカル社製のSILASTIC(登録商標)SH52U等のシリコンラバーが例示される。
図1に示すように、カメラモジュール1は、例えば車載カメラの駆動モジュールユニットであり、外部コネクタ400と接続される。
外部コネクタ400としては、FAKRA規格の同軸タイプのものが例示される。
上部ケース310及び下部ケース320は、コネクタアセンブリ10及びグランドシェル200を収容する空間を内側に画定している。
上部ケース310及び下部ケース320の材料としては、PBT樹脂(ポリブチレンテレフタレート樹脂)等の樹脂が例示される。
嵌合部311の内部には、コネクタ挿入穴312が形成されている。コネクタ挿入穴312には、後述するコネクタアセンブリ10のコネクタ100が挿入される。
嵌合部311の外周面には、外部コネクタ400を係止するための突起311aが形成されている。
パッド161は、後述するリフローはんだ付けを行ったときに、コネクタ100と電気的に接続される箇所である。
パッド161は、少なくともコネクタ100の底面形状(図6において一点鎖線で図示)を含む領域に設けられている。
外部端子110は、上鍔部111、下鍔部112及び台座部113を有している。
上鍔部111は、下鍔部112と共に後述する外ブッシュ120の位置を規制する機能を有している。
上鍔部111の上面は、外ブッシュ120の挿入を容易にするために、テーパ状に形成されている。
下鍔部112は、上鍔部111と共に後述する外ブッシュ120の位置を規制する機能を有している。
図7及び図8に示すように、台座部113の正面には、外部端子110の内部空間(筒状の内部空間)に連通する開口113aが形成されている。この開口113aには、コンタクトピン140の脚部142が挿通される。
図7から図9に示すように、台座部113の底面には、軸線Xを中心とした円周方向に複数の切欠き113bが形成されている。この切欠き113bには、リフローはんだ付けを行ったときに溶融したはんだが流れ込む。これにより、はんだが接触する面積を増やし、はんだ付けによる接合強度を向上させることができる。
台座部113の上面は、グランド面113cとされており、グランドシェル200に形成された複数のグランドピン210(図2参照)が接触する。これにより、外部端子110をより確実に接地させることができる。
カット面111aは、上鍔部111の外周面の一部が切り落とされたように形成された平面である。カット面112aも同様である。
カット面111a及びカット面112aは、平面視したとき、軸線X中心とした円周方向において、開口113aから覗くコンタクトピン140の脚部142と同位置に形成されている。これによって、平面視したときに、脚部142の状態(はんだ付けの状態)の視認性が向上する。
外ブッシュ120は、端子挿入穴121及び凸条部122を有している。
変形していない状態の端子挿入穴121の内径は、外部端子110の直径(上鍔部111と下鍔部112との間の外部端子110の直径)よりも小径とされている。これによって、外ブッシュ120に外部端子110を挿入したときに、外ブッシュ120が外部端子110の外周面に密着した状態となる。すなわち、防水機能を発揮することになる。
凸条部122は、軸線Xを中心とした全周に亘って形成されている。
本実施形態の場合、凸条部122は、軸線X方向に2段構成とされているが、1段であっても3段以上であってもよく、外部端子110の仕様によって適宜変更できる。
変形していない状態の凸条部122の直径は、後述する上部ケース310に形成されたコネクタ挿入穴312の内径よりも大径とされている。これによって、外ブッシュ120が取り付けられた外部端子110をコネクタ挿入穴312に挿入したときに、外ブッシュ120がコネクタ挿入穴312の内周面に密着した状態となる。すなわち、防水機能を発揮することになる。
内ブッシュ130は、ピン挿入穴131及び凸条部132を有している。
変形していない状態のピン挿入穴131の内径は、コンタクトピン140の直径(棒状部141の直径)よりも小径とされている。これによって、内ブッシュ130にコンタクトピン140を挿入したときに、内ブッシュ130がコンタクトピン140の外周面に密着した状態となる。すなわち、防水機能を発揮することになる。
凸条部132は、軸線Xを中心とした全周に亘って形成されている。
本実施形態の場合、凸条部132は、軸線X方向に2段構成とされているが、1段であっても3段以上であってもよく、外部端子110の仕様によって適宜変更できる。
変形していない状態の凸条部132の直径は、外部端子110の内径よりも大径とされている。これによって、内ブッシュ130が取り付けられたコンタクトピン140を外部端子110に挿入したときに、内ブッシュ130が外部端子110の内周面に密着した状態となる。すなわち、防水機能を発揮することになる。
コンタクトピン140は、棒状部141及び脚部142を有している。
棒状部141には、係止爪141aが形成されている。係止爪141aは、コンタクトピン140をインシュレータ150に挿入したときに、インシュレータ150にくい込む突起である。係止爪141aによって、コンタクトピン140がインシュレータ150に固定される。
脚部142の先端は、接地端142aとされている。接地端142aは、基板160とはんだ付けされる部分である。
インシュレータ150は、ピン挿入穴151を有している。
ピン挿入穴151の内周面には、コンタクトピン140の棒状部141に形成された係止爪141aがくい込む。
すなわち、図10に示すように、まず、インシュレータ150の下方から、コンタクトピン140の棒状部141をピン挿入穴151に挿入して、脚部142がインシュレータ150に当接するまでコンタクトピン140を押し込む(図9参照)。これにより、棒状部141の先端がインシュレータ150の上面から突出する。
なお、図14に示す温度プロファイルは例示であり、使用するはんだの種類や実装する部品の面積等の仕様によって適宜変更できる。
使用されるはんだとしては、SAC305等の一般的な鉛フリーのクリームはんだ/ソルダーペーストが例示される。
T0:室温
T1:予熱温度(150℃以上180℃以下)
T2:はんだ付けの最低温度(200℃以上220℃以下)
T3:はんだ付けのピーク温度(250℃以上260℃以下)
である。
導線の固定は、テープ(耐熱性を有するもの)やはんだ付けによって行われる。
これにより、はんだが溶融して、その後、溶融したはんだが固化する。
圧縮永久歪は、JIS K 6249に準拠した試験によって測定される。
本実施形態の場合、圧縮永久歪は、17%以下であることが好ましい。
硬さは、JIS K 6253に準拠した試験によって測定される。
本実施形態の場合、硬さ変化は、±5%以内であることが好ましい。
図15には、SILASTIC SH52U及び比較品(一般的なシリコーンゴム)としてのXIAMETER(登録商標) RBB-6650-50の各指標がまとめられている。
ここで、所定の防水試験とは、防水規格IP69Kに準拠した防水試験である。
以下、組み立てられたコネクタ100を基板160に実装して、カメラモジュール1を組み立てるまでの手順について説明する。
なお、上記リフローはんだ付けの後に、基板160の裏面に対してもリフローはんだ付けで他の部品を実装してもよい。この場合、2回目のリフローはんだ付けの温度条件は、1回目のリフローはんだ付け(コネクタ100を実装するためのリフローはんだ付け)の温度条件よりも低い。1回目のリフローはんだ付けで固化したはんだが再び溶融することを回避するためである。
外部端子110と、外ブッシュ120と、内ブッシュ130と、コンタクトピン140と、を備え、外ブッシュ120及び内ブッシュ130は、基板160に実装するときのリフローはんだ付けの温度(例えば200℃以上の温度)に耐え得る耐熱性を有しているので、外ブッシュ120及び内ブッシュ130の機能(防水性)を保証しつつ、外ブッシュ120及び内ブッシュ130が設けられた状態のコネクタ100を200℃以上の温度環境とされたリフローはんだ付けによって基板160の表面に実装することができる。
